How this calculator works

Every row below is one of the twenty-four jars in the book, with the figure Chapter 10 arrives at for a family of four that cooks the way the table assumes. Two things make the number defensible, and both are yours to change.

The prices are neighborhood-supermarket prices — Kroger, Safeway — not warehouse-club or supercenter prices. If you shop at a large discount chain you’ll find several of these products cheaper than I’ve listed them, and your savings will be correspondingly smaller, because you were already paying less for the thing you’re replacing. That cuts the other way too: shop somewhere expensive and every number in the table gets better. Prices are illustrative U.S. figures checked in 2026; they vary by region and change over time.

Every row compares the same amount of finished food on both sides. Not a jar against a box — a pancake against a pancake, a pan of brownies against a pan of brownies, a cup of gravy against a cup of gravy. Where the box has something built in that we buy separately (the chocolate chips, the pasta, the beans), that cost is charged to our side. The “Compared at” column says what was made equivalent in each row. Two jars in the book don’t beat the store once you do that accounting — the Mac & Cheese Powder (§3.2) and the Beef & Bean Skillet Starter (§3.5) — and both count zero here, exactly as they do in the book.

What to edit. The “Times a year” column is the frequency the book assumed. Change it to how often your household would actually use that jar and the row recalculates. The “Saving per use” column is the book’s per-use figure at book prices; if you’ve priced the store product at your own store and want to push the number up or down, edit it. Your edits are saved in this browser and survive a reload. “Reset” puts the book’s figures back.

Don’t expect the total to match anyone else’s. The book’s worked example lands at about $500 a year; a household that bakes every weekend and eats oatmeal every morning will land higher, and one that only wants the seasoning shelf will land lower — and be right.

The Personal Price Book

The habit, in one line: in the aisle, on your phone, divide the price by the total ounces on the package and write the result down. Six ingredients later you have a personal price book; within a month you know instantly whether $8.99 for a bag of oats is a deal or a shrug. It is the single habit that separates people who think they’re saving money on bulk from people who actually are.

The twelve foundation ingredients are already filled in as rows. Enter a store, a package size and a price and the $/oz column does the arithmetic. Entries are saved in this browser.

Read this before you chase the lowest number. The lowest price per ounce is not the best purchase if half the tub goes stale before you reach the bottom. Baking powder is the one ingredient §1.4 tells you never to buy in bulk, for exactly that reason, and oats are a buy-what-you’ll-finish-this-season ingredient — pair this table with the Shopping List page.

How to use the label sheet

Tick the jars you built, set the date you built them, and print. Each label carries the four things the Batch & Label Protocol asks for — the mix name, the “just add” line, the made-on date and the best-quality-by date — with the shelf-life window from that recipe’s card already applied. The date on the label is a quality window, not a safety deadline: it’s the point past which the leavening weakens or the milk powder starts to taste of the cupboard, and the book uses “best quality by” everywhere for that reason. Never “use by”.

Print on plain paper and tape (painter’s tape peels clean off glass), or on 2 × 4-inch address labels — the sheet is laid out ten to a page to fit either. A fine-point permanent marker rated for tape and glass is the only pen that survives a kitchen; write anything you add by hand with that.

Whole jar or scoop? Every label says which. Seven mixes in the book go into the bowl whole; the rest are scooped by the cup or the tablespoon. The full grid:

Gift tags

A gift tag is a label with two more jobs: it has to tell a stranger what’s in the jar, and it has to look like you meant it. Chapter 9 §9.2 fixes six elements, in this order, and the tag builder prints all six:

1. The mix name.
2. Ingredients, with the major allergens called out — wheat and milk are the two that occur across the twelve foundation ingredients, and the tag names them plainly rather than hoping the recipient reads the list.
3. The “just add” line — what to add, how much, and how hot, in one sentence.
4. Made on and best quality by.
5. How to store it — lid on, cool and dry, dry spoon.
6. Who it’s from.

Tags print at 3 × 4 inches — roughly an index card, the honest minimum for a working “just add” line — four to a page, on card stock.

Making the jar look deliberate

The lid. A two-piece canning lid with a kraft-paper or fabric round trapped under the band: cut a 5-inch circle, cut it with pinking shears so the edge can’t fray, lay it over the flat lid, screw the band down over it. No sewing, no glue. Plain brown kraft looks better than most fabric and costs nothing. Skip the round entirely on a jar you’re mailing — it snags, slides, and arrives crooked.

Twine and ribbon are not the same signal. Cotton butcher’s twine reads as food and belongs on savory jars. Satin reads as gift shop and looks faintly wrong around a jar of gravy mix. Grosgrain is the compromise, and unlike satin it holds a knot. Three wraps around the neck, a square knot on the front, tails cut on a diagonal to about two inches. A bow on a cookie jar is charming; a bow on a steak seasoning jar looks like you weren’t paying attention.

Jar choice. Regular-mouth jars beat wide-mouths for gifting: a regular mouth has an actual shoulder and neck instead of being a tube, and the neck gives twine somewhere to sit instead of sliding down.

The pre-lid checklist — what makes a jar read as amateurish. All of it is fixable before the lid goes on.

• Adhesive residue from a peeled-off supermarket label — soak the jar twenty minutes in hot water with a drop of dish soap and it lifts in one piece. Scrubbing it half-dry is what leaves the gray smear.
• Condensation on the inside of the glass — means something went in warm. Only fix is emptying, drying, and refilling.
• A tag written in cursive, pencil, or ballpoint on kraft.
• Mixed jar sizes across one batch of gifts.

Mailing. Give a glass jar two inches of padding on all six sides and tape over the band so it can’t back off. For anything going more than a state or two, skip the glass entirely: fill a heavy freezer-weight pouch using the flat-pack method from §1.5, press the air out from the bottom up, and let the recipient decant.

Tag-making tools.

• Card stock, 65 lb (176 gsm) at a minimum. Regular printer paper curls, wicks ink, and goes soft in a humid kitchen. Kraft-brown card stock is cheap, forgiving, and makes almost any handwriting look deliberate.
• Cut tags to about 3 × 4 inches — roughly an index card, the honest minimum for a working “just add” line.
• Punch the hole in a corner, not the centre of the top edge. A corner hole pulls against two edges of the stock. A top-centre hole pulls against a quarter-inch of paper and tears the first time the tag catches on something.
• Ink that dries. A fine-point permanent marker — the same one from the §1.1 bench that writes on tape and glass — is the safest tool on kraft. Ballpoint skips on it, gel pen smears for a full thirty seconds, and pencil fades to nothing inside a year. Write the tags first and let them sit while you fill the jars.

Lids, compared

How the tracker works

Add a jar, pick the mix, enter the day you made it. The best-quality-by date fills itself in from that recipe’s shelf-life window, and the row changes color as the date approaches: green while there’s time, amber inside sixty days of the stamp — the same threshold the monthly restock uses for “goes to the very front of the shelf” — and red once it’s past. Past is not a safety verdict; it’s the point to run the leavening test on anything that rises and to use the jar where the rise matters less.

Jars are saved in this browser. The list is built for a shelf of eight to twelve active jars with the rest rotating — that’s the working size Chapter 1 §1.6 and Chapter 9 §9.5 both settle on. A twenty-four-row grid that implies you’re behind isn’t the point; a shelf you can see the whole of is.

The two-row shelf

• The front row is the working shelf: jars you’re scooping from this month.
• The back row is the deep shelf: sealed and untouched.
• Traffic runs one direction only. The deep shelf feeds the working shelf, and nothing ever moves back the other way.
• A jar that’s been opened stays on the working shelf until it’s empty.
• For a cabinet too shallow to hold two rows, use two shelves and treat the higher one as the deep shelf. Same rule, vertical.

The quarterly shelf hour

Four dates a year: the first Saturday of March, June, September, and December. If the tracker is doing its job you never need this chart — it’s the paper fallback, and it’s what the tracker’s dates are built from.

Four dates a year against a 6-month stamp means no jar can go more than three months unexamined, which is the margin that makes the whole thing work.

The 18-month group is made once a year and still gets the quarterly look, just with less urgency. The 6-month group is quarterly at most — make that jar when you know you’ll bake.

The nose test

Use your nose as a check alongside the best-quality date, not instead of it. These are the standard descriptors for how these ingredients go off:

The seasoning row is the one people miss, because nothing is obviously wrong. A blend that has quietly stopped smelling like itself will quietly stop tasting like itself too. The cardboard note in cocoa is the cocoa-butter version of the crayon note in milk powder — same chemistry, different fat.

Three habits that beat any routine

Three habits do more for shelf life than any calendar, and they cost nothing:

1. Never scoop with a spoon that’s touched anything wet.
2. Never open a jar over a steaming pot — the seasoning shelf especially, where onion powder pulls water out of humid air fast enough to turn a jar into a puck by evening.
3. Put the lid back on before you measure the next thing, not after.

If a jar cakes anyway: clumping by itself doesn’t prove spoilage, but moisture exposure is one of the things that causes it — so look and smell before you use it rather than assuming it’s automatically fine. A caked jar that looks and smells normal usually just needs breaking up with a fork, and that is the single most common reason a perfectly good jar of homemade mix ends up in the trash instead.

Why every stamp is a hedge

Keeping added fats out of the jar removes one important source of quality loss, but it isn’t a guarantee on its own: storage time still depends on the specific ingredients and conditions in each jar. Every stamp in the book is a conservative window based on standard food-safety guidance for shelf-stable dry ingredients, not a deadline and not a test result. A boxed mix with the fat already built in — the kind that lets a brownie box say “fudge” on the front — holds a year or two rather than indefinitely, for exactly the reason this system keeps fat out of the jar.

Two jars worth knowing the “why” for: the Blueberry Muffin Mix (§5.3) is the most stable jar on the breakfast shelf — no fat, granulated sugar rather than brown, and baking powder with no soda alongside it to worry about; the milk powder is the only limiting factor. The Hot Cocoa Mix (§6.1) has milk powder at under a third of the jar, which is why it stamps at 12 months where §3.2 and §4.3, both more than half milk powder by volume, stamp at 9.

The master list

The twelve foundation ingredients, and nothing else, go in a jar. Everything fresh — eggs, butter, oil, milk, fruit — is added at the bowl, exactly as with any boxed mix. The checklist above ticks off in this browser and prints clean. The three tiers are the book’s starter budgets from Chapter 1 §1.6 — $25 tests whether your family eats this food, $50 is the tier the book is built around, $100 is the unit-price play — and the quantities are what it takes to build one jar of every mix that tier unlocks, summed straight from the Recipe Cards and rounded up to a package you can actually buy. Pick the tier that matches what you’ll build in the first month, not the one that sounds most thorough; most households settle at eight to twelve active jars.

Two things the book says about buying that are worth repeating on the list itself. Baking powder is the one ingredient §1.4 tells you never to buy in bulk: a dead can ruins a year of jars, and by USDA FoodKeeper figures it holds about six months unopened and about three months opened for best quality. Oats are a buy-what-you’ll-finish-this-season ingredient, for the reason under “Buying and storing bulk oats” below. The rest scale well — the alliums spectacularly so at restaurant supply — and the price-per-ounce habit from the Personal Price Book is how you decide how far to scale.

Restaurant supply. Access rules vary by chain and location — Restaurant Depot, WebstaurantStore, Smart & Final and regional cash-and-carry outlets. Many are open to the public or require only a free business membership. Worth one phone call before you drive out, since this is the channel where the garlic-and-onion-powder economics actually flip: three-ounce supermarket jars run $18–22 a pound; a five-pound restaurant-supply jug runs $4–6. Illustrative ranges checked at major U.S. chains in 2026, not fixed prices — check the unit price at the store you use.

Repackaging bulk buys

Repackage the day you get home, not the weekend you get around to it. A 25-pound paper sack of flour on a garage floor is an invitation to pantry moths and humidity both. Split it into gallon jars, a food-grade 2-gallon bucket, or heavy freezer bags within a day.

Home food-storage guidance commonly recommends freezing dry goods before you repackage them, to help control pantry pests that may have come in with the grain — a few days at 0°F is the range extension services point to, and it costs nothing.

Buying and storing bulk oats

Cool, airtight storage slows flavor loss significantly compared with a warm bag opened and closed all summer on the counter. Buy oats in quantities you’ll finish in a season and keep the bulk bag cold.

Why oats behave differently from flour on the shelf. An oat flake has been pressed flat for the express purpose of increasing its surface area, and its natural oil sits on the outside of that flake. That oil is what gives good oatmeal its sweet, faintly nutty smell straight out of the canister — and what turns flat and crayon-like when it oxidizes. Refined all-purpose flour carries much less natural fat, which is most of why the Chapter 2 baking mixes hold a year while two of the four Chapter 5 stamps say six months.

The monthly restock list

A restock runs under $30 once you’re past the first shop, and the reason is that you’re buying two or three ingredients, not twelve. Two columns on the back of an envelope, or in the box above:

The jars that come due most often carry the six-month stamp — Banana Bread & Quick Loaf, the oatmeal base, the granola base. The ones that rarely ask for anything carry eighteen months: Gravy & Sauce Mix, Classic Steak & Roast Seasoning, Onion Soup Mix, Hearty Bean Soup Base.

Your $40 bench

Chapter 1 §1.1 sets out the bench: a digital scale, a six-quart bowl, a balloon whisk, a canning funnel, measuring cups and spoons, a fine-point permanent marker, and a fine-mesh strainer. About forty dollars if you own none of it, and most kitchens own half. The checklist above ticks off in this browser. Three items carry a spec the book no longer has room to spell out:

Digital kitchen scale. Beyond the flat platform, the tare button and one-gram precision the book asks for, check one more thing in the store: the display should not sit directly underneath the weighing platform. On cheap scales it does, and once a wide mixing bowl is on the plate you can no longer read your own numbers. A display on a lip, an arm, or a pull-out tab solves it.

Large mixing bowl. Six quarts minimum. Stainless over glass for two reasons: it doesn’t chip, and it washes and dries faster between back-to-back batches — which matters because the wash-up between mixes is the thing that doubles the length of a batching session.

Permanent marker. Fine point, and specifically the kind rated to write on tape and glass without smearing. A standard office marker beads on a jar and rubs off on a sleeve.

Jars and lids

Glass is the book’s default — not because it’s scientifically superior, but because it’s durable, easy to label, and easy to inspect. Regular-mouth jars for gifting (they have a neck for twine); wide-mouth for anything you scoop from daily. Lids compared:

Freezer-weight bags are for two jobs only — single-batch portioning (one bag of pancake mix per Saturday morning) and packing mixes into a cooler, camper or cabin. Press the air out from the bottom up before you seal, and stand the bags upright in a shoebox so they don’t slump into an unstackable pile.

Small kitchen, RV, apartment

Vertical space. Measure the gap between shelves, not the cabinet. Jar heights: quart ≈ 6¾ in · pint ≈ 5½ in · 4-oz jelly jar ≈ 2½ in. Clip-on under-shelf wire baskets (~$8 a pair) hold four jelly jars each in the dead air above a short jar. A door-mounted rack does the same job on the inside of the cabinet door — it’s the best home for Chapter 4’s seasoning blends in a cabinet with no spare shelf gap. Buying jars new for a rectangular shelf: square beats round. Every round jar leaves four empty corners, and across a small cabinet that adds up to a whole jar’s worth of nothing.

Flat storage, when even a pint won’t fit. Heavy freezer-weight vacuum pouches or resealable stand-up sachets, filled with a half batch and pressed thin, stack like files — the shelf that held four quart jars holds close to twenty.

A pouch doesn’t index itself. Three habits:

1. Write the label along the bottom edge, before you fill the pouch.
2. Stand them upright in a shoebox so they read like a card index.
3. Split by use — jars for the mixes you scoop from repeatedly, pouches for the ones that go into the bowl whole (the Skillet Soda Bread and Banana Bread mixes are the two clearest examples).

Sealing tools, for the long-term shelf

• A $20 hair straightener is the cheap tool that genuinely works for Mylar — clamp and draw it slowly across the bag, then run it again a quarter inch below the first pass.
• A household clothes iron on a wooden board works too, on the cotton setting, pressed against a strip of parchment.
• Past about twenty bags, buy an impulse sealer. They run $25 to $40 and they’ll do a straight seal every time without you having to think about it.
• A vacuum sealer’s $10 jar attachment is the part of that system worth owning — for the dairy-heavy jars you can’t Mylar. The bags themselves are polyethylene and oxygen-permeable, which makes vacuum sealing a months tool rather than a years tool.

The time budget

Add up the mixing time each chapter states for its own recipes and the whole book comes to about three hours of whisking — twenty-four mixes across twenty-seven containers.

Saturday runs baking → breakfast → dessert: thirteen mixes, roughly an hour and three quarters of hands-on time spread across a day. Sunday runs dinner → seasonings: eleven mixes.

Three hours is the mixing. The rest of the weekend is setup, weighing, labeling, cleanup and two coffees. The checklist below ticks off in this browser, so you can run it from a phone on the counter.

Friday night — fifteen minutes

• Wash and dry every jar and lid, upside down on a towel overnight.
• Tear a strip of painter’s tape into pieces and write the mix names now, while your hands are dry and clean.
• Run the leavening test from §1.3 on the powder and soda you’re about to commit to a year of jars — baking powder: half a teaspoon into a quarter cup of hot water, it should erupt immediately; baking soda: a quarter teaspoon into two teaspoons of vinegar, same.

Finding out your baking powder is dead on Friday night costs you a trip to the store. Finding out in March costs you a batch of biscuits.

Saturday, session one — the baking shelf (Chapter 2, ~40 minutes)

• Set out 4 quart jars.
• Work in the printed order: All-Purpose → Buttermilk Biscuit → Skillet Soda Bread → Banana Bread.

That order runs driest and blandest to wettest and sweetest, which is why all four can be whisked in one unwashed bowl — stray flour dust in banana bread mix is invisible, and brown sugar residue in your baking mix is not.

Saturday, session two — the breakfast shelf (Chapter 5, ~35 minutes)

• Set the thirty snack bags out, open and standing, before you start blending oats. Eight of the thirty-five minutes in this session are portioning, and that budget assumes the bags are already open — not being hunted for mid-batch.
• Order: pancake mix → oatmeal base → muffin mix → granola base last.

It goes second because it works the same flour-and-sugar territory the baking shelf just left in the bowl. Store the finished stack of packets inside one larger airtight container rather than loose in a drawer; a thin bag on its own doesn’t hold up over months the way a jar does.

Saturday, session three — the dessert shelf (Chapter 6, ~30 minutes)

• Set out 5 jars.
• Follow the bowl, not the chapter order: streusel → cookie mix → yellow cake → brownie mix → hot cocoa.

Chapter 6’s printed section order starts with hot cocoa, but its bowl advice is “flour to cocoa, driest to richest,” and the two pull in opposite directions. For a full weekend run, follow the bowl. Cocoa dust in a yellow cake mix shows. Flour dust in cocoa doesn’t.

Sunday, session four — the dinner shelf (Chapter 3, ~50 minutes)

Set out, before you start:

• Start with the Cream of Anything base in a genuinely clean bowl — it’s the one savory mix that regularly ends up in something sweet. After that the bowl can stay dirty through the rest of the chapter; savory mixes forgive each other, and stray onion powder in the casserole starter is a rounding error.
• Budget about fifteen of the fifty minutes for dividing the casserole starter into four half-pint jars on a scale.

The longest session, because five mixes become eight containers.

Sunday, session five — the seasoning shelf (Chapter 4, ~25 minutes)

• Savory to sweet, wiping with a dry paper towel between jars, dessert sprinkle last. One unwashed bowl for the whole chapter. Nobody wants garlic in their toast sugar.

The fastest session of the weekend: no flour to fluff, and nothing to sift but the cocoa in the last jar.

Sunday afternoon — the part nobody schedules

• Label every jar with two dates: made on, best quality by. (The Labels page prints them.)
• Shelve them oldest to the front.
• Tape the five shelf-life charts from the ends of Chapters 2 through 6 inside the cabinet door where the jars live.
• Photograph the finished shelf, badly, on your phone. You’ll want that picture for the before-and-after page in §10.4, and in six months you won’t be able to reconstruct what the shelf looked like before.

The one-morning version

The shelves are independent. If you have one free morning rather than two days, build Chapter 2 and Chapter 3 — nine mixes, about ninety minutes. The seasoning shelf takes twenty-five minutes and can happen any weekday evening while something else is in the oven. The dessert shelf can wait until you want it.

Allergen exception: a gluten-free or other allergen-specific adaptation from Chapter 8 gets its own clean session, with tools that haven’t touched wheat flour that day. Never fold it into the one-unwashed-bowl flow above.

Sub-portioning a jar into single-dinner units

Two mixes in Chapter 3 are worth breaking down further than the recipe card does, for the same reason the casserole starter ships in four half-pints: on the night you need dinner, you don’t want to be measuring.

Weigh, don’t eyeball. Salt is more than a tenth of the casserole mix by weight, so a portion that runs heavy or light lands directly on the seasoning of a whole 9×13. Fill each jar to the shoulder: less air stored with the mix is part of what holds the stamp at a full year.

The three batching sessions, for restocking

Once the shelf exists, you don’t rebuild it all at once. You restock in sessions that share an open jug and a bowl:

• The allium session. Gravy & Sauce (§4.1), Onion Soup (§4.4), Ranch (§4.3), Bean Soup Base (§3.4). One jug of onion powder open, one of garlic, and §4.7 clocked the whole Chapter 4 shelf — six jars — at about twenty-five minutes.
• The flour session. All-Purpose Baking (§2.1), Buttermilk Biscuit (§2.2), Skillet Soda Bread (§2.3), Pancake & Waffle (§5.1). Driest to sweetest, one bowl, no washing between. The Chapter 2 opener runs four of these in about forty minutes.
• The sweet session. Chocolate Chip Cookie (§6.3), Yellow Cake (§6.5), Brownie (§6.4), Hot Cocoa (§6.1) — in that order, because anything with cocoa in it goes last or the pale jars pick up dust.

A single jar still makes sense the first time you try a mix, or for a half-batch of an adapted recipe you’re testing. The batching rule is about restocking efficiently; it is not a rule against ever making one jar.

The monthly restock: thirty minutes

The book explains why the routine exists — drift, not difficulty. This is the half hour itself. Set a monthly reminder; the checklist resets itself each time you open it after thirty days.

Minutes 0–5 — pull everything forward

• Take every jar off the shelf and onto the counter. This is the only way you’ll find the jar that drifted to the back months ago and stopped existing as far as your hand is concerned.
• Read the best-quality date on each one as you set it down.
• Anything inside sixty days of its stamp goes at the very front, where your hand lands first (§7.4’s rotation, at the scale of a single shelf).

Minutes 5–10 — write the list

• Two columns: jars that are empty or nearly empty; ingredients needed to refill them. (The Shopping List page has the box.)

A restock runs under $30 once you’re past the first shop, and this list is why: you’re buying two or three ingredients, not twelve.

Minutes 10–15 — test the lift

• Any jar carrying leavening that’s past month ten gets the right test for what’s in it:

Nothing you do in the bowl brings a spent leavener back.

A dead jar is not garbage. Weak leavening is a quality issue, not a safety verdict on its own — if the mix otherwise smells and looks normal, with no sign of moisture, pests or mold, it’s still fine to eat. Use it where the rise matters less, like pancakes or dumplings, and don’t spend it on biscuits.

Minutes 15–30 — remix two or three jars

• Remix what’s empty. That’s all a normal month needs, and it’s fifteen minutes because you’re not setting up a production line: one bowl, one whisk, the ingredients already on the counter.

The leavening potency check — one card

The book teaches this test twice (§1.3 on the raw ingredient, §2.5 on a stored jar). Once, clearly, for the cabinet door:

This is a potency check on the leavening, not a food-safety test. If a jar smells off, the fizz test is not the tiebreaker.

The book explains why you’d bag at all, which mixes are worth bagging and which are not, the three-tier structure, and why it refuses to attach a year count to a blended mix. This page is procedure and sizing: what to do on bagging day, and how much of each jar a month actually takes.

Safety lives in the book, not here. Chapter 7 §7.3 carries the carbon-monoxide guidance, the USDA figures for how long a refrigerator and freezer hold without power, and the “Cold chain?” reordering for the 30-day plan. Read it there before you rely on any of this. The one line worth repeating because Week 3 below mentions a grill: charcoal and gas grills, camp stoves and generators are for outdoors only — never inside a house, garage, basement or closed trailer, and at least 20 feet from windows, doors and vents even outside.

Part 1 — Mylar bagging: the full procedure

Tape this inside a cabinet door on bagging day.

Choosing the bag

Choose a food-grade foil-laminate pouch built for long-term dry-food storage, with enough puncture resistance for what you’re storing. A thin, flimsy bag is more likely to puncture on a corner of dry pasta or a bucket rim, and you won’t know until you open it.

Sizing the absorber

Absorber sizing depends on container volume, product density, headspace, and residual oxygen — always follow the absorber manufacturer’s sizing chart rather than a single rule of thumb. The table below is a rough illustration of how the sizing logic works, not a formula to apply blindly.

Rolled oats need more absorber capacity than flour because a flake traps far more air around itself than a flour granule does — a gallon of oats is mostly the space between the oats. Anything you’ve packed down tight, or any jar you’ve filled to the shoulder with almost no headspace, needs less. When in doubt, follow the absorber manufacturer’s guidance rather than improvising — an undersized absorber leaves oxygen in the bag with no easy way to tell.

Working fast: the five-step sequence

Oxygen absorbers start working the second you open the outer package, which means the sequence matters more than the technique.

1. Fill and line up every bag first, tops open, before you cut the absorber pack. Label each one on the outside with a permanent marker while it’s still empty and flat — writing on a full bag is a losing proposition.
2. Heat-seal each bag across the top, leaving a two-inch gap at one end. Do this before the absorbers go in.
3. Cut the absorber package. Work down the line, dropping one into each bag through the gap.
4. Finish the seals. All of them, then check your count against the number of absorbers you opened.
5. Anything left over goes immediately into a small canning jar with a two-piece lid, tightened down. Not a zip-top bag — a zip-top bag will not hold them, and a strip of absorbers left on the counter overnight is a strip of small rusty bricks in the morning.

Sealing tools

• A $20 hair straightener is the cheap tool that genuinely works — clamp and draw it slowly across the bag, then run it again a quarter inch below the first pass.
• A household clothes iron on a wooden board works too, on the cotton setting, pressed against a strip of parchment.
• Past about twenty bags, buy an impulse sealer. They run $25 to $40 and they’ll do a straight seal every time without you having to think about it.

Headspace: leave yourself a way back in

Leave two or three inches of empty bag above the seal. That’s your opening allowance: you cut below the seal, use what you need, and re-seal underneath the cut. A bag sealed right at the fill line can only be opened once.

Where the bags stand

Mylar keeps oxygen out; it does not keep teeth out, and a mouse will chew through a bag on a garage floor without much trouble. If the storage location isn’t a clean interior closet, stand the bags inside a food-grade bucket or a hard-sided tote.

What a firm bag does and doesn’t tell you

Some bags become noticeably firmer as the oxygen is removed — a properly sealed bag doesn’t collapse into a vacuum, it just draws in and goes firmer over the first twelve to twenty-four hours in many cases. But appearance alone isn’t a reliable seal test: headspace, bag flexibility, product density, and absorber size all affect how firm a bag ends up looking. If you want more certainty than a visual check gives you, that’s a reason to be generous with absorber size and careful with the seal itself, not to rely on firmness as proof.

Part 2 — Vacuum sealing a powder: the cuff

Fine powder gets pulled up the bag by the vacuum and into the seal channel, and a seal with flour in it looks fine and fails within a week.

The fix: fold the top four inches of the bag back into a cuff before you fill it, so the seal zone stays clean, then unfold it just before sealing.

The book keeps the principle: vacuum-sealer bags are polyethylene laminate and therefore oxygen-permeable, which makes vacuum sealing a months tool rather than a years tool — and the $10 jar attachment is the part of the system worth owning, for the dairy-heavy jars you can’t Mylar.

Part 3 — The full 30-day quantity table

Thirty days, family of four. The book keeps only the four lines that run deeper than people expect (§2.1, §2.3, §5.1, §5.2) plus the reasoning; this is the whole shelf. Tick what you have.

Part 4 — Weeks 2 and 3, written out day by day

The book keeps Week 1 (the cycle as written), Week 4 (the jar-and-can week) and a prose digest of what changes in between. These are the two middle pages.

Week 2 — the same shape, every jar’s second use

• Day 1 → the same skillet, in bowls instead of over rice, with rice saved for later in the month.
• Day 2 → chicken casserole rather than tuna (§3.3), with canned chicken.
• Day 3 → lentil soup, no soak — the third way to use §3.4 — with soda farls instead of the loaf, which is the stovetop version of §2.3 and needs no oven at all.
• Day 4 → if you still have cheese, cheese sauce for vegetables (§3.2’s third use) poured over rice and a can of green beans; once the cheese runs out, the same base thinned into a plain white sauce over rice with canned vegetables covers the same slot.
• Day 5 → cream of mushroom (§3.1) over egg noodles.
• Day 6 → pot roast with the Onion Soup Mix (§4.4) if you have meat and a covered pot; French onion soup with toasted soda bread if you don’t.
• Day 7 → pancakes for dinner (§5.1), which is a real meal and also a morale decision.

Week 3 — the seasoning shelf comes forward

By now the dinners want variety more than they want calories. The three protein-based nights below assume you still have some meat to season — from a chest freezer that’s stayed cold, meat bought or bartered fresh during the week, or canned meat worked into the same seasoning. If none of that applies, the Steak & Roast Seasoning and the Grill Rub both fall back to their vegetable and potato uses, and the week leans harder on the Chapter 3 mixes instead.

• Ranch chicken (§4.3), 2 tablespoons per pound, roasted or pan-seared.
• Steak & Roast Seasoning (§4.2) on roasted potatoes, which is that jar’s third listed use and the one that matters most when there’s no steak.
• Brown Sugar & Garlic Grill Rub (§4.5) on pork or chicken thighs, over charcoal — outdoors, per the note at the top of this page — if the power’s out and you’re cooking on a grill anyway, this jar is suddenly the most useful thing in Chapter 4.
• Green bean casserole (§4.4 stirred into a batch of §3.1) as a full dinner rather than a side, with rice under it.
• The Chapter 3 mixes fill the rest of the week on the same shape as Week 1.

Host a mix party: the run-of-show

The book keeps the two rules that prevent failure — a scoop never crosses between bins; label the jar before the next one gets filled — and the principle that everybody builds the same mix at the same time. This is the full station setup and the timeline the host tapes to a cabinet door.

The four stations

Station 1 — Weigh. One or two scales, the ingredient bins for the current mix only, and a dedicated scoop living in each bin. Never let a scoop cross between bins; a scoop that’s been in the brown sugar and goes into the flour brings moisture with it. Tape an index card with that mix’s weights in grams to the table so nobody has to hold six numbers in their head over the noise of eight people talking.

Station 2 — Whisk. Bowls and balloon whisks, at least four of each so there’s no queue. Ninety seconds of hard whisking per bowl, per §1.1. This is the station that needs the most floor space, because a six-quart bowl and a swinging elbow take more room than people plan for.

Station 3 — Fill. Funnels and the guests’ own jars. Fill to the shoulder, tap the jar twice on the table to settle it, seal.

Station 4 — Label. Markers, tape or labels, and one person who does nothing else. Label the jar before the next one gets filled — never at the end, when everyone is tired and eight identical jars of beige powder are sitting on a table with nothing to distinguish them. This is the easiest way to end an afternoon with jars nobody can identify.

The jar moves. The people stay.

What to have on hand

Multiply the recipe by the number of guests, then add ten percent, because some of it lands on the table and some of it misses the funnel. The calculator above does that for three mixes; here are the worked examples at eight guests, so you can see the line item that will surprise you — there’s one in each.

The baking mix eats half a ten-ounce can of baking powder — the one ingredient §1.4 told you never to buy in bulk, and the one you’re most likely to run out of mid-party. The cookie mix takes very nearly a whole four-pound bag of brown sugar. And the cocoa column is why hot cocoa is the priciest jar in Chapter 6: two and a half pounds of milk powder for eight pints.

The timeline

Splitting the money — three models

The assignment list — best for a first party. Each guest is told one ingredient to bring, in a stated quantity, and everyone shows up having spent roughly the same. Nobody fronts money, nobody has to trust anyone’s arithmetic, and the host doesn’t spend a Saturday morning at three stores. The cost is that somebody will forget the salt.

Host buys, everyone settles up after — best once it’s a habit. One shopper, one receipt, one trip to the restaurant supply store where the actual savings live, divided by heads at the end. This is the only model that captures the five-pound-jug economics, which is the whole reason for the party. Do it once the group has proven it shows up.

Flat fee per head. Eight to twelve dollars a person, host handles everything, no receipts and no arithmetic. It’s the cleanest socially and the least precise financially. Perfectly good for a group that would rather not talk about money.

Host’s checklist

• Six to eight guests invited; five mixes chosen
• Every guest asked to bring: their own jars and lids, plus their §1.1 bench (scale, six-quart bowl, balloon whisk, canning funnel, measuring cups and spoons, fine-point permanent marker)
• Money model decided and stated in the invitation
• Painter’s tape and a marker by the door for initialling jar bases on arrival
• One person assigned to labels only; one assigned to the strainer during the soda and cocoa mixes
• Index cards written with each mix’s gram weights, taped to the weigh station
• No kettle, no dishwasher, nothing on the stove; window cracked; coffee made in another room
• A separate clean station and bench set aside for any gluten-free or allergen-specific jar, run before or after the main line — never alongside it
• One fresh bowl per mix (no reusing across eight bowls in motion)

Teaching kids to mix

The rule that comes before the chart

Never let a child taste raw flour, a dry mix built on flour, or raw dough or batter. Flour is a raw agricultural product. The FDA is specific that raw flour can carry bacteria like E. coli or Salmonella, the same way raw dough can, and grinding or bleaching doesn’t kill anything — only baking or cooking does. This applies to the adult holding the spoon as much as to the child watching. Salt and sugar are the safe exception; anything flour-based, and anything with raw egg in it once activated, stays off-limits until it comes out of the oven or off the griddle.

What a kid can actually do, by age

These are typical starting points, not developmental rules — every kid and every household is different, and the right age to hand something over depends on maturity, prior kitchen experience, and your own comfort level more than the calendar.

Whisking. A balloon whisk in a narrow bowl at five years old is a mess-making machine, because the arc of the whisk hits the wall and throws powder up and out. Give a young child a wide, shallow bowl and half the volume an adult would use. The physics change completely and so does the amount of flour on your floor.

Labelling is not a consolation prize. §1.2 established the label as the thing that makes the entire system function — a jar without one becomes, within about three weeks, a jar nobody will risk. Handing a child the label is handing them the load-bearing part. Say so.

First projects, in order of how well they land

1. Homemade Hot Cocoa Mix (§6.1) — four ingredients, no leavening, forgiving proportions, one strainer step, and a payoff that arrives ten minutes after the lid goes on. Warning: milk powder goes in last, bowl tilted away, or a fast whisk puts a cloud of it on a small person’s face.
2. Granola Base (§5.4) — the single best kid job in the book: rubbing oats, brown sugar and salt together by hand for two minutes. A child can do the whole procedure. The baking (300°F oven, hot sheet pan) is an adult’s job.
3. Chapter 4 seasoning blends — nothing rises, nothing sets, nothing collapses if a measurement is a little off. Salt needs an adult double-checking; the rest tolerates a light hand. Classic Steak & Roast Seasoning (§4.2) is two minutes of work; Cocoa-Sugar Dessert Sprinkle (§4.6) is three ingredients that go onto toast the same morning.
4. Hearty Bean Soup Base (§3.4) — for a slightly older kid who wants to make something for dinner rather than dessert: five ingredients, hand-rubbed, an eighteen-month stamp, and it turns into a pot of soup that feeds the family.

Projects to save for later, and why

• Anything with a baking soda strainer step — Buttermilk Biscuit (§2.2), Skillet Soda Bread (§2.3). An unsifted lump of baking soda is soapy and bitter, and because it stays a lump it lands in one bite of one biscuit rather than spreading across the batch. A child cannot reliably tell “all the way through” from “mostly through,” and there’s no checking afterward. Age nine and up, or do the strainer step yourself and hand them everything else.
• Anything where the leavening ratio is tight — All-Purpose Baking Mix (§2.1) at one and a half tablespoons of baking powder against three cups of flour; Blueberry Muffin Mix (§5.3) is no more forgiving. A heaping tablespoon instead of a level one is a twenty-five percent error in the one ingredient with no tolerance. Level-off technique first.
• Instant Oatmeal packets (§5.2) — thirty identical measurements into thirty bags. An endurance problem rather than a skill one, and it ends somewhere around packet nine. Fine for a teenager with headphones on.
• Mac & Cheese Powder (§3.2) — half milk powder by volume, which means it’s half cloud, at counter height, in somebody’s face.

The three rules, for the fridge

1. Ingredients are for measuring, not tasting. (Full rule at the top of this page. Salt and sugar are the exception — taste them side by side so they learn the difference, since they look identical in a bowl.) Skip the baking soda taste test entirely: no safety issue in a small taste, no reason for it either, and it’s an easy habit to just not start.
2. Dry hands, always, and no fingers back in the jar. Not for reasons of germs — §2.5 and §3.6 both make the point that a wet scoop kills a jar faster than age does. Nothing wet touches the mix, including you.
3. Their jar, their name, their choice. One mix per session, not four. A jar with their handwriting on it, on the shelf, at their eye level. Under twenty-five minutes for anyone under seven. The mess isn’t the failure mode — boredom is.

The long versions of things the book gives you the short version of: option grids, doneness cues, the variations that didn’t fit, and a handful of technique notes that answer the questions readers actually send.

Casserole Starter (§3.3) — build-your-own grid

The book keeps the method and two named versions. The full option grid:

Doneness cue for the 9×13: 25–30 minutes at 375°F. It’s done when the sauce bubbles at the center as well as the edges — push a spoon into the middle and look — and the top has browned in patches. Rest 5 minutes before serving so it sets enough to cut.

Chicken pot pie with a biscuit top — the long version

The book gives the ratio change and the steam rule. The rest of the detail:

• Sauce arrives thicker because there’s no pasta in the dish drinking up liquid in the oven: whole jar into 2 cups of cold broth rather than 2½, same 3 Tbsp butter, whisk 4–5 minutes.
• Off the heat, fold in 3 cups diced cooked chicken and 2 cups vegetables — frozen peas and carrots straight from the bag, or whatever’s in the crisper cut small enough to cook through in half an hour.
• Biscuit top: one batch from the Buttermilk Biscuit Mix (§2.2) or the All-Purpose Baking Mix (§2.1), mixed a touch wetter than usual so it slumps and spreads. Eight rough spoonfuls, gaps left between them.
• Vessel: buttered 9×13, or a deep 10-inch skillet.
• Full doneness cue: 400°F, 25–30 minutes, until the biscuits are deep gold and split across the top and the filling bubbles up around their edges.

Bean and lentil variations for the Hearty Bean Soup Base (§3.4)

The base always goes in the same way and at the same point: ⅓ cup whisked smooth into 1 cup of the hot broth, stirred back into the pot, 10 more minutes at a gentle simmer.

Cheese sauce for vegetables (§3.2’s third use)

Shorter, thicker version of the Mac & Cheese base: ⅓ cup mix, ¾ cup cold water, 2 Tbsp butter, 4 oz cheese. It has to cling to a floret rather than coat a noodle.

Targets: steamed broccoli or cauliflower · a split baked potato · a plate of roasted carrots.

Finishers that aren’t among the twelve

Kept out of the jars on purpose, but worth a line if you already own them. Anything outside the Foundation Twelve goes in at the bowl or in the liquid, never into the jar — cinnamon in the cocoa pot, cinnamon in the oatmeal bowl, black pepper on the steak seasoning, vanilla in the cookie dough. Two reasons: ground spices gradually lose aroma after opening, and a spice stored against brown sugar in a sealed mix clumps besides. Added at the bowl, an outside ingredient costs nothing on shelf life and the recipe works either way.

Freezer-flat portioning

Applies to the Beef & Bean Skillet (§3.5) and to anything else you cook in a full batch and eat in quarters.

• Cool the batch, press it into a zip-top bag, freeze it lying flat, not standing up.
• A flat bag has far more surface for its volume than a block does. It loosens in a low skillet in minutes; the same portion frozen in a block sits there long enough for the bottom to catch before the middle gives.
• Flat bags stack like files in a freezer door. A rounded container never does.
• Window: 3 months. A weeknight dinner becomes a reheat instead of a cook.

Granola: baked vs. the unbaked base

Adding dried fruit shortens the window because moisture migrates out of the fruit and into the oats, and the clusters you worked for can go soft within days. To keep granola longer, freeze it plain and add the fruit and chocolate by the bowlful as you eat it. It thaws in four minutes on the counter and comes back crisp.

The cocoa paste step, in full

Cocoa powder doesn’t dissolve well in a large volume of liquid all at once; it needs a concentrated, hot, well-stirred head start. That’s the whole reason every cocoa activation in the book begins with 2–3 tablespoons of just-boiled water and a smooth paste before the rest of the liquid goes in. Stirred straight into a full mug — or worse, into cold milk — the powder barely wets and leaves a gritty layer at the bottom.

Troubleshooting: cocoa tastes thin no matter how much mix you add → the fix is the paste step, not more mix.

Scaling a mug to a slow cooker. The slow-cooker cocoa is the single-mug ratio scaled up, nothing more: 2 cups mix into 1 cup hot water (the same paste), then 5 cups of milk. Keeping the mix-to-liquid ratio identical is what makes any of these jars scale cleanly.

Portioning single-serve packets

Thirty snack bags at ⅓ cup apiece is about eight minutes of work. Set the bags out open and standing before you start blending oats — the budget assumes you aren’t hunting for them mid-batch. Store the finished stack inside one larger airtight container rather than loose in a drawer; a thin bag on its own doesn’t hold up over months the way a jar does.
