Start here Essentials
At minimum, read a thermometer in the fridge and one in the freezer, make one fridge shelf the eat-first shelf, and write two lists: what is in the freezer and the staples you want on hand. The full pantry clear-out can wait.
- Put an appliance thermometer in the fridge and one in the freezer, read them, and turn the control if a reading is above target (thermometers).
- Clear one fridge shelf and make it the eat-first shelf (the eat-first shelf).
- List what is in the freezer with the date each went in, or "date unknown" (the freezer list).
- List the pantry by category, roughly; a cupboard shelf counts (the pantry).
- Write ten staples you want on hand every week (staples).
Minimum time: about 45 minutes, plus a second reading the next day if you turned a control. Done when: the temperature sheet has a reading for both appliances (at target, or with the adjustment noted), and the freezer list exists.
1. Thermometers and target temperatures Understand
"Using what you have" starts with knowing what you have and whether it is being kept cold enough. Temperature comes first because every storage time in How long food keeps assumes it. The federal targets are a refrigerator at 40 °F (4 °C) or below and a freezer at 0 °F (-18 °C) or below (FDA, Refrigerator Thermometers; USDA FSIS, Refrigeration and Food Safety).
The reason for the fridge number is bacterial growth. FSIS says some bacteria can double in number in as little as 20 minutes between 40 °F and 140 °F (60 °C), the range How long food keeps calls the danger zone, and that a refrigerator at 40 °F or below protects most foods. Cold slows growth; it does not stop all of it. Freezing at 0 °F stops bacteria from growing but does not kill them, so food that thaws is handled like any other perishable food (USDA FSIS, Freezing and Food Safety).
Why the control dial is not enough
An appliance thermometer is a thermometer made to stay inside a refrigerator or freezer and show the air temperature there. It is not the same as a food thermometer, which is pushed into food to check how hot it is. FDA's thermometer page says few refrigerator controls show actual temperatures and recommends an inexpensive freestanding appliance thermometer, one in the fridge and one in the freezer. A dial marked 1 to 5 or "colder" and "coldest" says which way to turn, not where the temperature is; your appliance's manual says what its settings mean. Product-specific
FDA's storage guide says to place the thermometers in the front of each compartment, where they are easy to read, and to check them at least once a week (FDA, Are You Storing Food Safely?). For the freezer, University of Illinois Extension describes a reading method: set the thermometer between frozen packages, wait 5 to 8 hours, and if it does not read 0 to 2 °F, adjust the control and read again after another 5 to 8 hours (University of Illinois Extension, Freezer Storage). That is one extension service's method. For the fridge, we use the same idea: leave the thermometer in place several hours or overnight and read it before the door has been opened much, such as first thing in the morning. A reading taken just after a long look for a snack, or after a full bag of groceries went in, runs warm.
Reading, adjusting and reading again
- Read both thermometers and write the date and both readings on the temperature sheet.
- If the fridge reads above 40 °F or the freezer above 0 °F, turn that control one step colder and tick "Control adjusted". One step at a time keeps you from overshooting into frozen lettuce.
- Read again after several hours or the next day, and write a second row.
- Repeat one step at a time until the reading is at target, then read once a week, as FDA advises.
If a fridge cannot reach 40 °F at its coldest setting, or a freezer will not hold 0 °F, the appliance needs attention from its manufacturer or a repair service; the thermometer has done its job by showing it. FSIS says a freezer compartment that cannot hold 0 °F is for short-term storage only. Texas A&M AgriLife Extension gives a household check that needs no thermometer: if the freezer cannot keep ice cream brick-solid, it is not cold enough (Texas A&M AgriLife, Safe Home Food Storage). A thermometer reading is more exact. Test it
Outside the US. Target temperatures come from each country's food agency. The UK's Love Food Hate Waste campaign, run by WRAP, gives 0 to 5 °C (about 32 to 41 °F) for a fridge. If you live outside the US, use your own agency's figures for temperatures and storage times and use this manual for the method.
Warmer and colder spots. A fridge is not one temperature. Moving the thermometer to a different shelf for a day shows how much your own fridge varies from top to bottom and front to back. Michigan State University Extension calls the bottom shelf the coldest and the door bins the place where temperature changes most.
2. Fridge zones and the eat-first shelf
Where food sits in the fridge matters for two reasons: some places are warmer or less steady than others, and raw meat can drip onto food that will not be cooked. The sources agree on the main points:
| Zone | What goes there | Why | Source |
|---|---|---|---|
| Door | Condiments, pickles, jams, drinks | The warmest or least steady place in the fridge; not milk or eggs | EPA; Michigan State; FSIS |
| Upper and middle shelves | Ready-to-eat food, leftovers, dairy, eggs in their carton | More even temperature than the door; above anything raw | Michigan State; FSIS |
| Bottom shelf | Raw meat, poultry and fish, in a container or on a plate | The coldest shelf, and below other food, so drips land on nothing | EPA; Michigan State; FoodSafety.gov |
| High-humidity drawer | Vegetables that wilt: leafy greens, carrots, cucumbers, broccoli | Keeps moisture in | EPA |
| Low-humidity drawer | Most fruit, and vegetables that rot, such as mushrooms and peppers | Lets moisture out; keeps fruit apart from vegetables | EPA; Michigan State |
EPA's page on preventing wasted food at home says the door is the warmest part of the fridge, that condiments can go there but milk and eggs should not, and that the lower shelves are the coldest, for meat, poultry and fish (EPA, Preventing Wasted Food at Home). FSIS says not to store perishable foods in the door and to keep eggs in their carton on a shelf. FoodSafety.gov keeps raw meat, poultry and seafood in containers or sealed leakproof bags, and Michigan State puts meat on a plate or in a bowl in case it leaks (Michigan State University Extension, Know where to put what in your refrigerator).
The crisper drawers are the closed drawers at the bottom of most fridges; some have a slider that opens or closes a vent. A closed vent keeps humidity high, which suits leafy vegetables; an open vent lets humidity out, which suits most fruit. Michigan State says not to keep fresh fruit and vegetables in the same drawer because, in its words, fruits produce the most gas; How long food keeps explains that gas, ethylene. If your fridge has one drawer, give it to the vegetables that wilt and keep fruit on a shelf. The produce section in How long food keeps says which fruit and vegetables belong in the fridge. Product-specific
Two more rules apply everywhere in the fridge. FDA says not to crowd it so tightly that cold air cannot circulate. And Michigan State says to label food with the date it went in, which is what lets the eat-first shelf and the storage card work: a container without a date has to be guessed at.
While you sort the fridge, keep perishable food out of it for as short a time as you can. FSIS's limit is 2 hours at room temperature, or 1 hour above 90 °F (32 °C); work one shelf at a time and put things back as you go. If you find food you are unsure about, do not taste it to find out: FSIS says to never taste food to determine its safety, because food that makes people sick can look, smell and taste normal. When in doubt, throw it out, and record it in the waste log with its reason.
The eat-first shelf
EPA's Food: Too Good to Waste toolkit includes an "Eat First" sign: a household sets aside one area in the refrigerator for leftovers and food that will not keep long, and puts the sign there as a reminder (EPA, Food: Too Good to Waste toolkit). The eat-first shelf is that area. It works because food at the back of a shelf is easy to forget, and a fixed place for what is running out of time puts it where everyone looks.
Choose a shelf, or the front half of one, that is at eye level and above any raw meat. Clear it, wipe it, and label it with tape: "Eat first". What goes there:
- Leftovers, with the day they were cooked on the lid.
- Opened packages: an opened jar of sauce, half a can of beans moved to a container, sliced deli meat.
- Produce that is ripe or close to the end of its life.
- Anything the storage card (How long food keeps) gives the shortest time.
The shelf is a place, not a rule about what is still good to eat. Something on it still follows its storage time; the shelf only makes sure it is seen before that time is up. The weekly plan starts every weekly plan by reading this shelf. If your baseline week (Your starting week) is still running, set the shelf up on the day after the week ends, so the baseline stays an ordinary week; the thermometers can go in now.
The fridge list
An inventory is a written list of the food on hand, kept so a household knows what it has before it plans or shops. Michigan State's guide to organizing food storage works one area at a time: take everything out, wipe the shelves, group like items to spot duplicates, and keep a simple list by category, which, it says, makes a grocery list easier because you see at a glance what you are out of (Michigan State University Extension, Organizing food storage areas). The fridge sheet takes the item, the date it went in, an eat-by day, and an eat-first tick. On a first pass the fridge list can be rough: the eat-first items and the leftovers matter most, because they change every week.
Where the warmest zone is. EPA's page says the door is the warmest part of the fridge. Michigan State's says the top shelf is the warmest and the door bins have the least steady temperature. Both keep milk and eggs off the door, and both put meat on the bottom. The difference likely depends on the fridge; a thermometer moved from shelf to door for a day shows which is true of yours. FSIS's advice, not to store perishable food in the door, holds either way.
3. The freezer list
The freezer is where food is easiest to lose track of: packages are frosted over, stacked, and often unlabeled. The National Center for Home Food Preservation (University of Georgia) says to post a frozen-foods inventory near the freezer, list each food and the date it was frozen as it goes in, and check items off as they come out; it also groups foods by kind and uses the oldest first (NCHFP, Freezer Management). The freezer sheet follows that: item, date frozen, servings, a "quality by" date, and a "used" tick. Print it, or write it on paper, and keep it on or near the freezer door.
Most kitchens start with food that has no date. Write "date unknown" rather than a guess. A missing date does not make food unsafe, and it does not make it fine either; it means the quality is unknown. FSIS says food kept constantly at 0 °F stays safe indefinitely, and that its freezer storage times are for quality only: frozen food slowly loses moisture, flavor and texture (USDA FSIS, Freezing and Food Safety). The safety part depends on the freezer having held 0 °F the whole time, which the thermometer readings now start to show.
Freezer burn is the grayish-brown, leathery patches that form where frozen food dries out. FSIS calls it a quality issue, not a safety one, and says the affected parts can be cut away before or after cooking. Food with heavy freezer burn is a fair candidate for an early meal or the waste log; it is not a reason to fear the rest of the freezer.
A small freezer on top of or beside the fridge opens with every visit to the fridge. If yours reads above 0 °F, FSIS treats it as short-term storage; the freezer list is then also a reminder to use what is in it sooner. How long food keeps gives each food's freezer time as a quality limit, and Prep and batch cooking adds what you freeze on prep day to the same list.
The inventory records what is there; it does not decide whether a food is still safe to eat. A "date unknown" burrito, a jar at the back of the shelf or a dented can is written down as it is. How long each food keeps, and whether its limit is about safety or quality, is How long food keeps and the storage table. Do not taste food to test it, as the caution above says. A bulging, leaking or badly dented can goes out without tasting. When in doubt, throw it out.
A chest freezer map. A chest freezer hides whatever is at the bottom. Draw a plan of it from above, divided into the baskets or layers you have, and write which kinds of food go in each: meat at the bottom left, bread in the top basket, cooked meals on the right. Keep the map with the freezer list. NCHFP's grouping by kind is what the map puts on paper.
Filling and emptying. NCHFP says a full freezer is the most energy-efficient, and that filling and emptying it two, three or more times a year lowers the cost per package stored. A freezer half full of forgotten packages costs the same to run as one that is used. A freezer that is cleared and refilled on a rhythm (an eat-down before a big shop, for example) keeps the list short.
4. The pantry, cans and staples
A pantry, here, is wherever shelf-stable food lives: a closet, a cupboard, one shelf. Shelf-stable food is food that can be stored at room temperature before it is opened: canned and bottled foods, rice, pasta, flour, sugar, spices and oils, and foods in sealed cartons or pouches. Some canned ham and seafood is labeled "Keep Refrigerated" and is not shelf-stable, so read the label. FSIS says shelf-stable food keeps best in a cool, dry place, that temperatures below 85 °F (29 °C) are best, and that temperatures above 100 °F (38 °C) are harmful to canned goods (USDA FSIS, Shelf-Stable Food Safety). Texas A&M's home storage guide gives a narrower ideal of 50 to 70 °F (10 to 21 °C) for a pantry that is dry, cool and dark, and keeps food away from the range, oven, water heater, dishwasher and hot pipes.
FSIS lists places not to keep cans: above or beside the stove, under the sink, and in a damp garage or basement. Heat speeds up the loss of quality, damp rusts cans, and the cupboard under a sink can be both. If your only cupboard is beside the stove, use it for things that keep longest, such as dry pasta in a sealed container, and keep cans in the coolest spot you have.
The pantry sheet lists items by category: grains and pasta, beans and lentils, canned, baking, oils and vinegars, spices, condiments, snacks, other. Group the shelf the same way, so the list and the shelf match. Write an amount ("2 cans", "half a bag") and the date anything was opened. On a first pass, a rough list is enough; the full clear-out is under Go deeper.
First in, first out means putting new items behind the ones already there, so the older ones are used first. Michigan State's guide and Texas A&M's both teach it. Texas A&M adds two points that matter for a meal plan: buy food in reasonable amounts, because excess food may become waste, and buy only staples you expect to use within their recommended storage times, even when they are on sale. FSIS says to check the pantry every few weeks.
When to discard a can
Most dents are harmless. FSIS says a small dent is fine, but a deep dent (one you can lay a finger into) and any dent on a seam mean the can should be thrown out, because the seal may be damaged. Heavy rust that does not wipe off means discard; light surface rust that wipes away is fine. A can that is swollen or bulging, leaks, hisses loudly or spurts when opened, or has a foul smell or milky liquid inside goes out. FSIS lists these as warning signs of botulism.
Throw away cans that bulge, leak, spurt, or are deeply dented or dented on a seam, without opening or tasting the food. FSIS's botulism warning says not to even taste food from a container showing these signs. These rules are for commercial cans. This manual does not teach home canning; for home-canned food, follow the National Center for Home Food Preservation.
A damaged can goes on the waste log with the reason "other" and a word in the notes. It is not counted as a planning failure; it is recorded so the week's amount stays honest. How long an undamaged can keeps, unopened and opened, is in the pantry times in How long food keeps.
The staples list
Staples are the foods a household wants on hand all the time, because many meals start from them. A master list is a shopping list that is kept from week to week instead of rewritten. Nebraska Extension's grocery-list guide puts the "must have" items permanently on a master list and has you circle each one when you need it (Nebraska Extension, Use a Grocery List). Iowa State's Spend Smart. Eat Smart. keeps a master list of weekly staples posted where people can jot down items as they run low (Iowa State, Shopping Tools).
The staples list is the short version of the pantry: not everything you have, but what you do not want to run out of. For a starting set, Nebraska Extension's mix-and-match planning method stocks a few versatile basics that combine into many meals, the way a few clothes mix into many outfits: fruit, cheese, eggs, frozen vegetables, milk, meat, poultry or fish, and rice and pasta (Nebraska Extension, Mix and Match Meal Planning Strategy). The page notes that many people do not decide what to have for dinner until 4 p.m. or later; staples are what make a late decision possible without a trip to the store. The staples sheet starts with that set plus oil, salt and pepper. It is your list to change: cross off what your household does not use and add what it does.
Ten items is a workable size for a first list. For each one, the sheet has "Have now" (plenty, low, out) and an "Add to list" tick. Shopping and budget builds the shopping list from the staples marked low or out. The sheet's "Keep at least" column is your choice, set from how fast your household uses each item.
| Sheet | What it holds | First pass |
|---|---|---|
| Temperatures | Date, fridge and freezer readings, whether a control was turned | Essential: two readings, more if adjusted |
| Fridge | Item, date in, eat-by day, eat-first tick | Rough: eat-first items and leftovers |
| Freezer | Item, date frozen (or "date unknown"), servings, quality by, used | Essential: everything in the freezer |
| Pantry | Item, category, amount, date opened | Rough: by category |
| Staples | Item, keep at least (your choice), have now, add to list | Essential: ten items |
| Storage card | Each usual food's fridge, freezer and pantry times, marked safety or quality | How long food keeps |
A full pantry clear-out. Follow Michigan State's order, one area at a time. Take everything off the shelves and wipe them. Group like items and count duplicates. Check every can against the dent, rust and swelling rules above. Put back oldest in front. Food you will not use that is unopened and in good condition can go to a food pantry; Michigan State suggests donating unneeded, unexpired food. List what goes back on the pantry sheet.
"Keep at least" amounts. A household that runs out of rice twice a month might set "keep at least 1 bag"; one that buys a large bag and loses it to pests might set "half a bag". These are our suggestions, not published figures. Set them from your own weeks, and lower any amount that leads to food going past its time.
5. Shared shelves and allergy shelves
In a kitchen where people keep different food, assigned space prevents two problems: eating someone else's food and losing track of your own. For a household with a food allergy it has a third purpose, keeping the allergen away from the person it affects. FARE (Food Allergy Research & Education) advises assigning specific pantry and refrigerator shelves, storing food in sealed containers, and labeling either the problem foods or the safe ones, whichever is easier, for example with colored stickers (FARE, Tips for Keeping Safe at Home).
For the inventory, that means:
- A shared house: one shelf or bin per person and one shared shelf, in the fridge and the cupboard. The fridge and pantry sheets get the owner's name in the item column ("Kai: yogurt"). Shared staples go on one staples list that everyone can mark low. Leftovers carry a name and a date (Leftovers and using it up).
- A food allergy: a set shelf for the allergy-safe foods, above anything that contains the allergen, in sealed containers, with labels everyone in the household can read. Which foods are safe for the person, and how strict the household needs to be, is decided with their allergist; The people at your table covers labels and cross-contact, and this manual does not manage an allergy.
- A medical diet or food rules: a labeled shelf can help, and the rules themselves come from the person's doctor, dietitian or tradition, not from the inventory.
The house on Alder Street (one of this manual's fictional cases; details invented) has one refrigerator with a shelf for each of Kai, Noor and Ben and a shared shelf; a small top freezer; and one cupboard each plus a shared cupboard. They share staples (rice, oil, spices, coffee, milk, eggs). Their eat-first shelf is the front half of the shared shelf. Their staples list holds the shared staples only; each person keeps their own pantry list for their cupboard. Who pays for which staple is a question for the housemates to settle, and Shopping and budget covers the budget side.
6. See it: Jordan's kitchen inventory See it
Jordan Pike (29, lives alone; they/them) is one of this manual's fictional cases; the temperatures, items and results here are invented. Jordan has a refrigerator with a top freezer, one cupboard shelf for food, an oven and a microwave, and shops on Saturday.
Known.
- Thermometers: Jordan buys two appliance thermometers and sets one in the front of the fridge and one between packages in the freezer. The next morning the fridge reads 43 °F (6 °C) and the freezer 0 °F (-18 °C). Jordan turns the fridge control one step colder and ticks "Control adjusted". The next day the fridge reads 39 °F (4 °C) and the freezer 0 °F again. The temperature sheet has two rows.
- Eat-first shelf: the top shelf, at the front, labeled with tape. Two leftover containers and an opened jar of pasta sauce go there. Raw chicken, when Jordan buys it, will go on the bottom shelf in a container.
- Freezer list: a bag of frozen peas, two burritos ("date unknown"), half a loaf of bread.
- Pantry: one shelf, listed roughly by category: rice and pasta; canned black beans and tomatoes; oil, salt and pepper; a box of crackers.
- Ten staples: eggs, milk, rice, pasta, canned black beans, canned tomatoes, frozen vegetables, cheddar, oil, and salt and pepper (counted as one).
Assumed. That the 39 °F reading holds. One reading after one adjustment is a start, not proof: Jordan's assumption until more readings agree.
Open, and who settles it. Whether the fridge stays at 40 °F or below after the change: next week's reading settles it. Whether the two burritos are still good: with no date, their quality is unknown; FSIS says food kept constantly at 0 °F stays safe, and Jordan decides whether to eat them soon or let them go after How long food keeps. This manual does not judge them. Whether the staples list fits: Jordan's next few shopping trips show what runs out.

7. Practice: readings, a shelf and two lists Practice
Minimum: one reading for each appliance (a second if you turned a control), one eat-first shelf, the freezer list and ten staples. Time: about 45 minutes, plus a minute the next day. Materials: two appliance thermometers (one for the fridge, one for the freezer), tape and a marker, a cloth for wiping a shelf, and the inventory sheets on screen or printed.
- Place the thermometers. Fridge thermometer at the front of a middle shelf; freezer thermometer between packages. Leave them several hours or overnight.
- Read and record. Write the date and both readings on the temperature sheet. If a reading is above target, turn that control one step colder and tick "Control adjusted".
- Clear one shelf. Take everything off one shelf, wipe it, label it "Eat first", and put back only leftovers, opened packages and food close to its time. Keep each item out of the fridge as briefly as you can.
- Check the zones. Move milk and eggs off the door, put any raw meat on the bottom shelf in a container, and give the crisper drawers to vegetables and fruit separately.
- List the freezer. Take items out a few at a time, write each with its date or "date unknown" on the freezer sheet, and put them back grouped by kind.
- List the pantry roughly by category on the pantry sheet, and check any dented, rusted or swollen cans against the rules above.
- Write ten staples on the staples sheet, marking each plenty, low or out.
- Read the thermometers again after several hours or the next day if you turned a control, and add the row.
- Clear out the whole pantry in Michigan State's order and rebuild it first in, first out.
- Map the warm spots: move the fridge thermometer to the door for a day and to the top shelf for a day, and note the readings.
- Draw a freezer map if you have a chest freezer, and set "keep at least" amounts for your staples.
8. Your kitchen Your kitchen
9. Check your work Check your work
Criteria
- Does the temperature sheet have a dated reading for the fridge and the freezer, taken after the thermometers had been in place for several hours?
- Is each reading at target (40 °F or below, 0 °F or below), or is there a turned control and a second reading?
- Is there one labeled eat-first shelf above any raw meat, holding leftovers and food close to its time?
- Are milk and eggs off the door, and raw meat on the bottom shelf in a container?
- Does the freezer list name every item with a date or "date unknown"?
- Does the staples sheet have about ten items, each marked plenty, low or out?
Worked example
Jordan's inventory (fictional) meets each criterion. The temperature sheet has two rows: 43 °F and 0 °F with "Control adjusted" ticked, then 39 °F and 0 °F the next day. The top shelf's front is labeled "Eat first" and holds the leftovers and the opened sauce. The freezer list has three items, with the burritos marked "date unknown" rather than guessed. The staples sheet has ten items. The criteria do not ask whether the fridge holds at 39 °F; one more week of readings settles that.
Common mistakes
- Reading the fridge thermometer right after putting it in, or right after the door was open for a while. Leave it several hours.
- Turning the control several steps at once and freezing the lettuce. One step, then read again.
- Treating "date unknown" as "unsafe" or as "fine". It means the quality is unknown; How long food keeps gives the times.
- Putting the eat-first shelf below raw meat, or at the back where nobody looks.
- Making the staples list a copy of the whole pantry. Staples are only what you want on hand all the time.
What is still unresolved
The inventory says what is in the kitchen and how cold it is kept. It does not say how long each food keeps or whether anything on the shelves is still good: the storage card in How long food keeps does that for your usual foods, and this manual does not judge any specific item. Whether the fridge holds its temperature is settled by the weekly readings, and whether the staples list is right is settled by the next few shopping trips.
