Guides
Honest, unhurried answers to the questions people actually type in at 6pm with the fridge door open. No shaming, no rules to follow — just the reasoning, so you can make your own call.
How long does opened milk really last? A practical answer
The printed date describes an unopened carton. Once opened, a different clock starts — here is how to read it.
Best before vs use by: what food dates actually mean
One is a quality estimate you can safely overrule. The other is a safety limit. Knowing which is which changes what you throw away.
Why expiry reminder apps get abandoned (and what works instead)
The problem is never willpower. It is that the effort comes first and the payoff comes later — here is how to invert that.
What to cook with what I have: deciding dinner in two minutes
The block is rarely cooking. It is deciding. A simple ordering turns an open fridge into a short list.
How long do leftovers last in the fridge? A realistic guide
Cooking resets the clock. It does not stop it. Here is the window that actually applies, and why your nose is the wrong tool for checking it.
Does freezer burn mean food is unsafe to eat?
The pale, dry patches look like something went wrong. What actually happened is moisture left and did not come back — a quality problem, not a safety one.
Why you keep buying food you already have
The duplicate is rarely a memory failure. It is a timing failure — the knowledge was fine, it just never got asked the question at the right moment.
Are eggs still good after the date on the carton? A practical answer
The date on a carton of eggs is usually the most cautious number on it. Here is what actually determines how long eggs keep, and how to check for yourself.
Can you refreeze meat after it's thawed? The actual rule
The rule people half-remember ("never refreeze meat") is more cautious than it needs to be. What actually matters is how the meat thawed, not whether it thawed.
How to plan meals around what you already have
The usual version starts with a list of dishes and shops to match. The version that actually survives the week starts with what is already there.
How long does raw chicken last in the fridge? A realistic window
Raw chicken has the shortest fridge window of any common meat, and that has little to do with how fresh it looked in the shop. Here is what actually decides it.
What vegetables and fruit should not be stored in the fridge?
Cold is not a universal upgrade. For a specific list of vegetables and fruit, the fridge is where the flavour or the shelf life quietly gets worse — here is why, food by food.
Why does food get forgotten at the back of the fridge?
It is not a discipline problem. Food at the back of the fridge falls out of the memory you use daily, and the fridge is built in a way that stops you rediscovering it by accident.
How long do opened condiments really last in the fridge?
One group of condiments is built to resist bacteria on its own. The other is fresh food that happens to be sold in a jar. Here is how to tell which is which.
How long does opened hummus last in the fridge? A practical guide
Hummus is closer to a fresh dip than a shelf-stable condiment. Here is what actually decides how long an opened tub keeps.
What does the sell-by date on food actually mean?
Sell-by is a stocking instruction aimed at the shelf, not a countdown aimed at your kitchen. Mixing the two up is why perfectly good food gets binned early.
How to use up random ingredients before they go bad
One odd leftover ingredient is a harder decision than a whole meal, because it does not fit any dish you already had in mind. Here is what actually absorbs it.
Does buying food on sale actually save you money?
The sticker prices the food. It does not price whether you will actually eat it — and that second number is the one that decides whether the deal saved you anything.
Where should you actually store food in the fridge?
The door is the warmest, least stable part of the fridge. The bottom shelf is the coldest. Most of us store food by whatever shape fits, not by zone — here is what changes when you match the two.
Why do some foods not have an expiration date?
A blank space where a date should be is not an oversight. It means the food is stable enough, by a specific set of chemical reasons, that a date would not be telling you anything useful.
How to feed a family without a meal plan
The plan is not the thing that feeds people. Knowing what is actually in the house, and letting whoever is around see it, does most of the real work.
How long does opened cheese last in the fridge?
A wedge of aged parmesan and a tub of ricotta are barely the same category of food once opened. Moisture content, not brand or price, is what actually decides how long each one keeps.
How long does a cut avocado last in the fridge?
A whole avocado ripening on the counter and a cut one in the fridge are running on two completely different clocks. Here is what governs the second one, and it is mostly about air.
Why does food get forgotten in the freezer?
The fridge sends you signals long before you forget something is there. The freezer sends none at all, which is exactly why what goes in so rarely comes back out.
Why does food get forgotten in the pantry?
Nothing in a pantry is spoiling on a schedule you can sense, so nothing ever forces you to look. That is not a smaller version of the fridge problem — it is a different one, with its own fix.
Why does food sometimes go bad before the date on the package?
The printed date describes a best-case unit tested somewhere else. Here is what causes the gap between that estimate and the food actually sitting in your fridge.
How long does cooked rice last in the fridge? Why it needs care
Rice carries a spore that survives cooking and does not announce itself by smell or taste. Here is why that makes cooling speed matter more than the calendar.
Does butter need to be refrigerated? What actually happens either way
Butter is high in fat and low in water, which makes it a poor host for the bacteria that spoil milk. Here is what the counter is actually safe from, and what it is not.
How to buy groceries less often without running out
Fewer trips only works if the kitchen has two different speeds running at once — one for things that will not wait, one for things that will. Most attempts collapse because they only plan for one.
How long do fresh herbs last in the fridge? A practical guide
Herbs are not one category with one shelf life. Tender and hardy herbs die on completely different clocks, and most of the wilting people blame on time is really a storage problem.
How long does opened yogurt last in the fridge? A practical answer
Yogurt starts its life full of live bacteria, so the printed date was already a conservative guess before you opened it. Here is what actually decides how long the opened tub keeps.
How long does ground beef last in the fridge? A realistic window
Ground beef keeps for a tighter, stricter window than a whole steak cut from the same animal — and the reason is about surface area, not freshness. Here is what actually decides it.
How long does opened deli meat last in the fridge?
Deli meat is cooked or cured before it ever reaches you, so it should be one of the safer things in the fridge. One organism changes that calculation. Here is what actually governs the window.
How long does fresh fish last in the fridge? A realistic window
Fresh fish has one of the shortest fridge windows of any common food, and the reason is built into the fish itself, not the shop. Here is what actually decides it.
How long do fresh berries last in the fridge? Why they mold so fast
The reason berries seem to turn overnight is not bad luck — it is built into how each one is put together. Here is the real window for each kind, and why washing them early makes it worse.
How long does bacon last in the fridge? A realistic answer
Curing buys bacon extra time in the fridge, but it does not stop the clock — and bacon can go wrong in two different ways, not one.
How long does cooked pasta last in the fridge?
The noodle is almost never the risky part. What is mixed into it — cream, seafood, egg, a splash of oil — is what actually sets the clock.
Does bread need to be refrigerated? What the fridge actually does to it
Cold speeds up how bread goes stale and only slightly slows how it grows mould — for most loaves, eaten within a few days, that is a bad trade.
How long do hard-boiled eggs last in the fridge?
Boiling strips away the protection that makes raw eggs last so long, so a boiled batch runs on a much shorter, separate clock — about a week in the shell, less once peeled.
How long does opened canned food last in the fridge?
A can's printed date describes the sealed tin. Open it, and a different, much shorter clock starts — here is how that one actually works.
Why you keep throwing away food you actually meant to eat
You did not forget this one. You had a plan for it. Here is why a real intention still quietly expires, and what actually keeps it alive until dinner.
How long do fresh mushrooms last in the fridge? Why they go slimy
A mushroom is a fungus, not a vegetable, and the sealed tray it is sold in is often the reason it turns slimy before its time. Here is what actually determines the window, and why cutting one shortens it so much.
How long does cooked chicken last in the fridge? A realistic window
The three-to-four-day window is the same as any leftover, but cooked chicken starts from a riskier baseline — and a rotisserie bird from the shop often arrives with part of that clock already used up.
How long does cooked salmon last in the fridge? A realistic window
The window is the same three to four days as any cooked leftover, but a fishy smell tells you far less here than it does with chicken — in both directions. Here is what actually decides it.
Why does feeling guilty about wasting food not help?
The guilt shows up while you are holding the evidence over the bin. The decision that caused it happened days earlier, somewhere else entirely — which is why feeling worse about it has never once changed what happens next time.
How long does raw pork last in the fridge? A realistic window
Pork keeps a stricter reputation than its actual fridge window deserves. Whole cuts behave more like beef than like chicken — here is what actually decides how long a chop or roast has.
How long do cut vegetables last in the fridge?
The moment you cut into it, a vegetable stops following the rules of the whole one. Here is the new clock that starts, and what actually slows it down.
How long can you keep food in the freezer before it goes bad?
Frozen food does not really "go bad" the way fridge food does — it quietly gets worse. Here is the difference between the safety clock and the quality clock, and roughly how long each one runs.
Why does frozen food still have a best before date?
Freezing pauses the clock that date was written for, but not every clock in the bag. Here is what the printed date is actually estimating, and why it stops being the useful number the moment you freeze something yourself.
How long does opened tofu last in the fridge?
A carton of tofu that never needed the fridge unopened, and a tub that always did, are not the same product once you break the seal. Here is what actually decides how long the opened block keeps.
Does peanut butter need to be refrigerated? What the jar is actually doing
A jar of peanut butter is mostly fat and protein with almost no water in it, which is exactly what makes it such an unfriendly place for bacteria to begin with. Here is what the fridge is really doing for it, and what it is not.
Does mayonnaise need to be refrigerated? The acid that makes it safe
Commercial mayonnaise is acidic enough to keep most bacteria from getting a foothold, which is not what its reputation suggests. Here is what the acid is actually doing, and why homemade mayonnaise is a different food entirely.
How long does lettuce last in the fridge? Why it wilts, browns or turns slimy
A whole head of lettuce and the same lettuce pre-chopped are not on the same clock. Here is what actually decides the window, and why the fruit sitting next to it in the crisper drawer matters more than people think.
How long do potatoes last before they go bad?
A potato kept somewhere cool, dark and dry can outlast almost everything else in the kitchen. Light, warmth and the fridge itself are what shorten it.
Do onions need to be refrigerated? What actually keeps them going
A dry, papery-skinned onion stored on the counter outlasts almost everything else in the kitchen. Cut it open and the rule flips completely - here is why, and what to do with each kind.
Do tomatoes need to be refrigerated? Why the fridge changes them
A ripe tomato does not spoil faster in the fridge. It just stops tasting like a tomato, and that part does not come back. Here is why, and the two real exceptions.
How long can food sit out before it is unsafe to eat?
The fridge clock and the counter clock are not the same clock. Two hours is the general guideline, and unlike spoilage, the bacteria that matter here rarely announce themselves.
How long does homemade soup last in the fridge? A practical guide
The fridge is not the part that catches people out. A big pot cools slower than it looks like it does, and that matters more than the day count.
How long does leftover pizza last in the fridge?
The window is a few days either way, but the box it arrived in — not the crust — is usually what shortens it.
How long does raw shrimp last in the fridge? A practical guide
Raw shrimp is one of the shortest-lived things in the fridge, and most of what looks fresh at the counter has already been frozen once. Here is what actually decides how long it keeps.
How to cook for one person without wasting food
The waste is rarely about eating too little. It is that recipes and pack sizes are both built for a household you do not have — here is what to do about the gap instead.
How long does opened orange juice last in the fridge? A practical guide
Pasteurised, shelf-stable and fresh-squeezed orange juice are three different products with three different clocks. Here is what actually decides how long an opened bottle keeps.
Does oat milk need to be refrigerated? Reading the carton correctly
A carton shape is not a storage instruction. Here is why some oat milk is fine unrefrigerated until opened, why some never is, and what happens the moment either one is opened.
Why does it feel like there's nothing to eat when the fridge is full?
A full fridge and "nothing to eat" are not actually a contradiction. One is about quantity, the other is about whether a meal has assembled itself yet — and it never does on its own.
How long does raw beef last in the fridge? Steaks and roasts vs mince
A whole cut keeps longer than mince from the same animal, and the reason is the same surface-area mechanism that makes ground beef spoil fast — just running in the other direction.
Can you still eat food after the best before date?
Passing the date does not flip a switch. For most best-before foods it means almost nothing at all — here is how to tell which kind you are actually holding.
How to use up what is already in your freezer
Nothing in a freezer forces a decision the way spoilage does in a fridge. That is exactly why it fills up and stays untouched — here is a method that does not depend on remembering what is in there.
How long does opened cream last in the fridge?
Fat and acidity, not freshness, decide how long an opened carton keeps — and the pack usually prints the one number that outranks any general rule.
How long does cooked turkey last in the fridge? A realistic window
The three-to-four-day window is the same as any cooked meat, but a whole bird cools slower and turns into several dishes — stuffing, gravy, stock, next week’s sandwiches — that do not all share one clock.
How long does opened pasta sauce last in the fridge?
Tomato pasta sauce is acidic enough to buy you real time, but not acidic enough to be treated like ketchup. Here is what changes once the jar is homemade, or has meat or cream stirred into it.
How long does opened salsa last in the fridge?
Jarred salsa and fresh salsa are not the same food safety-wise — one is built to last, the other is basically a salad. Here is what actually decides how long each one keeps once it is opened.
Why do households end up with duplicate groceries?
One fridge does not mean one shared memory. In a household, duplicate buying is not carelessness multiplied by the number of people — it is a coordination problem, and it needs a coordination fix.
How to make a grocery list from what you already have, not what you remember
A list built from what you remember buying and a list built from what is actually on the shelf are two different documents. Most people only ever write the first one.
How to read the date code on food packaging
A plain date and a lot code are printed for two different audiences. Learning to tell them apart stops a factory tracking number from getting read as a fast-approaching expiry.
How long do grapes last in the fridge? Why they turn so fast
Grapes do not fail one at a time the way you would expect from a whole fruit. Here is why a bunch spoils as a cluster, and what genuinely slows it down.
How long does opened kimchi last in the fridge?
Kimchi is already fermenting before you open the jar, so the usual "how long until it goes off" question does not quite apply. Here is what is actually happening inside the jar, and what to watch for instead.
How long does cooked shrimp last in the fridge?
Cooked shrimp keeps noticeably longer than raw shrimp did, but it is not a reset to zero. Here is what the cooking actually bought you, and what still decides the window.
Does soy sauce need to be refrigerated? What the salt is already doing
Soy sauce is a salty, fermented liquid that was never a comfortable place for spoilage organisms to begin with. Here is what the fridge is actually protecting against, and why it is mostly flavor rather than safety.
How long does opened wine last in the fridge? A practical answer
There is no date on the label for this one. What decides it is oxygen, type, and temperature — here is how long each kind of bottle actually has.
What does "use within 3 days of opening" actually mean?
Every other date on the pack was decided in a factory. This one starts on a day only you know — which is exactly why it gets lost.
Why do leftovers never get eaten?
They are already cooked and already yours, which should make them the easy choice. Here is why they quietly lose the evening anyway.
How long does fresh spinach last in the fridge?
Spinach is mostly water in a very thin leaf, which is why it turns faster than almost anything else in the drawer. Here is what actually controls the window, and the trick that lettuce cannot do.
How long does guacamole last in the fridge?
The brown layer on top of guacamole looks like the warning sign, but it usually is not the one that matters. Here is what actually spoils it, and how homemade and store-bought differ.
How long do carrots last in the fridge?
A carrot mostly fails by drying out, not by rotting — which is why a limp one is often still fine, and why whole, peeled and cut carrots really do keep for different lengths of time.
What to cook when the fridge is almost empty
An empty-looking fridge is a fridge judgement, not a kitchen judgement. Most of a real dinner is still sitting in the freezer and the cupboard, just not where you looked.
How long does sour cream last in the fridge, opened and unopened?
It is cultured, which buys it more time than milk or cream — but the tub is not immune, and the signs of it turning are easy to mistake for how it always looks.
Why do some best-before dates only show a month, not a day?
A date’s precision is itself a clue. The coarser it is, the more stable the food is expected to be — and the less it has to do with safety.
Does ketchup need to be refrigerated? What the vinegar and sugar are already doing
Ketchup is acidic and sugary enough that most spoilage bacteria struggle to get started in it, which is why an unopened bottle needs no fridge at all. Here is what the fridge is actually doing once the bottle is open, and which bottles do not get the same margin.
How long does opened pesto last in the fridge?
Pesto is not preserved the way ketchup or soy sauce is. Here is what the oil layer is actually doing, what garlic-in-oil means for a homemade jar, and how to tell normal aging from a jar that is done.
How long does cooked quinoa last in the fridge? A practical answer
A cooked grain is not the same food as the dry one in the jar. Here is why quinoa follows the same cooling and reheating rules as rice, and how long it actually keeps once it is cooked.
How to tell how old food is when the packaging is gone
The date was printed on the packaging, not on the food. Losing it costs you a reference point rather than safety information — and a reference point is something you can rebuild.
What temperature should your fridge actually be set to?
The dial almost never shows an actual number. Here is the temperature that matters, why it was chosen, and the one-time check that tells you what your fridge is really running at.
How long does cream cheese last in the fridge?
A tub of cream cheese rarely gets used up in one sitting, which is exactly why nobody notices when it quietly goes past its best. Here is what actually limits it once it is open.
How long does fresh ginger last in the fridge?
Ginger does not spoil the way most produce does — it dries out and then shrivels. Here is what actually slows that down, and why the freezer usually beats the fridge.
What does the "freeze by" date on meat actually mean?
It is not a new kind of date — it is a deadline stapled to the use-by date, marking the last day freezing still counts as a safe extension rather than a delay.
Why does meal prep still lead to food waste?
Meal prep solves the cooking decision and quietly creates three smaller ones in its place. Here is why the batch still loses, container by container.
How long does opened jam last in the fridge? A practical guide
Sugar and acid mean jam is built to last, but "built to last" is not the same as "immune." Here is what actually shortens the window, and why scraping off mould is no longer the right call.
How to avoid wasting food before you go on vacation
Packing gets planned for weeks. What happens to the fridge while you are gone almost never does — here is why that gap costs more than it should, and what to do about it before you leave.
Can you freeze milk? What actually happens when it thaws
Freezing milk is safe. What changes is texture, not safety — and knowing why explains what thawed milk is still good for.
Does garlic need to be refrigerated? What actually shortens it
A dry, unbroken bulb outlasts almost everything else in the kitchen sitting on the counter. Peel it, chop it, or leave it in oil, and the rules change fast — one of them for reasons that have nothing to do with freshness.
How long does cooked beef last in the fridge? Roast, steak and stew
Roast, steak, stew, mince-based dishes — once beef is cooked, they are all on roughly the same clock. The part that trips people up is a colour change that looks worse than it is.
What to do with half-used ingredients from a recipe
A whole ingredient has a home. A recipe fragment does not — which is exactly why it gets lost. Here is the one habit that gives it a second use before it needs one.
Does mustard need to be refrigerated? What the vinegar and mustard seed are already doing
Mustard has two independent defences against bacteria — an acidic environment and a seed that is naturally antimicrobial on its own. Here is what that means for whether it needs a fridge.
How to cook dinner without going grocery shopping
The fridge gets checked out of habit. The freezer and pantry usually do not — which is why "we have nothing" is rarely the whole truth.
Why is it awkward to throw away food in a shared fridge?
Throwing out your own leftovers costs nothing. Throwing out a housemate’s costs a small, awkward conversation you would rather not have — so the container stays, and rots for longer as a result.
Does honey ever go bad? What actually happens in the jar
Honey does not spoil the way most food does — but "basically never" is not the same as "no matter what you do to it." Here is the real mechanism, and the one failure mode that is genuine.
How long does opened coconut milk last in the fridge?
A can is rarely used all at once. Here is how long the rest of it keeps, and why the layer on top is not the problem.
How long do sweet potatoes last before they go bad?
A sweet potato kept cool, dark and out of the fridge lasts three to five weeks. Put in the fridge, it can develop a hard, off-tasting core and spoil faster once it comes back out — the opposite of what refrigeration usually does.
How long do bananas last before they go bad?
A banana on the counter and a banana in the fridge are both still ripening — just in different places. Here is what the peel is telling you, and what it is not.
How long does opened almond milk last in the fridge?
Opening the carton is what starts the clock, not the print on the side. Here is the window that actually applies once air gets in, and how to tell a normal separation from real spoilage.
Does maple syrup need to be refrigerated? Why it plays by different rules than honey
Maple syrup and honey sit on the same shelf and get treated like cousins, but one has noticeably more water in it than the other, and that gap is the whole story. Here is what actually changes the moment the bottle is opened.
How long does opened miso last in the fridge? Longer than you think
Miso arrives at your fridge already preserved by salt and fermentation, so an opened tub is measured in months, not days — the trick is knowing what to watch for instead of a date.
Why does shopping hungry lead to food waste?
A hungry brain is not undisciplined, it is answering a different question. It optimises for what would taste good in the next hour, not for what a week of meals actually needs.
Does salad dressing need to be refrigerated? It depends which one
A vinaigrette and a creamy dressing are not the same food wearing different flavours. One defends itself with acid the way a pickle does; the other is closer to mayonnaise. Knowing which is which changes what the fridge is actually doing for it.
Does soy milk need to be refrigerated? It depends on the carton
A carton of soy milk in the cereal aisle and one in the dairy case can look almost identical and still follow completely different rules — and fresh soy milk from a market is a third thing again, with the shortest window of all.
How long does opened tomato paste last in the fridge?
Most recipes use a spoonful and leave the rest of the can behind. Here is how long opened tomato paste keeps, and why the freezer, not the fridge, is where the leftover actually belongs.
How long does opened chicken broth last in the fridge?
The carton makes chicken broth look shelf-stable. Opened, it behaves more like milk than like a condiment — here is the real timeline, and what changes it.
How long do leftovers last in the freezer? A realistic guide
The freezer does not slow leftovers down. It stops them. What actually runs out on a shorter timeline is texture, not safety — here is the window that matters.
Does hot sauce need to be refrigerated? What the vinegar is already doing
Most hot sauce is chilies, vinegar, and salt — a combination that was never a friendly place for spoilage to start. Here is what the fridge actually adds, and why it is mostly about flavor rather than safety.
How long does cut watermelon last in the fridge?
A whole watermelon can sit on a counter for weeks. A cut one is playing an entirely different game, and it starts the moment the rind is breached.
How long do cucumbers last in the fridge?
A cucumber is one of the few fridge vegetables that can be genuinely too cold, not just too warm — and the usual crisper-drawer instinct is not quite right for it either.
How long do bell peppers last in the fridge?
A pepper's real enemy is dry air, not the cold — and a red or yellow one is already running on a shorter clock than a green one from the moment it is picked.
How long do apples last before they go bad?
Apples are one of the heaviest producers of ripening gas in the whole fridge, which decides both how long an apple itself lasts and what it quietly does to everything stored near it.
How long does cooked pork last in the fridge? A realistic window
Cooking feels like it should make food last longer, and for pork it barely moves the number at all. Here is why, and what actually decides how long a leftover chop or roast has.
How long does raw sausage last in the fridge? Fresh vs cured makes the call
A raw breakfast sausage and a stick of salami share a shape, not a shelf life. Here is why the label matters more than the casing, and the real window once you know which one you have.
Why does canned food still have a best before date?
The date on a can is a quality guess for a food that barely changes. The thing actually worth checking is not the calendar — it is the can itself.
Does olive oil go bad? Rancidity explained
Olive oil cannot really spoil in the bacterial sense — there is no water for anything to grow in. What it can do is oxidise, and that has its own clock, driven by light, heat and air rather than the calendar.
How to keep track of what is in your fridge
A list beats memory, but only if it gets updated at the moment something changes rather than reconstructed later from memory. Here is why that timing is the whole trick.
Why are expiration dates set earlier than they need to be?
The printed date is not a measurement of when food actually turns — it is a line drawn somewhere ahead of that point. How much room is in front of the line depends on which kind of date you are reading.
How long does broccoli last in the fridge? Why it turns yellow so fast
Broccoli ages faster than most vegetables in the crisper, and the fridge is usually not the reason. Here is what is actually driving the clock, and what yellow florets do and do not mean.
How long does rice last in the pantry?
White rice barely ages at all if it stays dry. Brown rice is a different case entirely, for a reason that has nothing to do with the calendar.
How long is food safe in the fridge during a power outage?
A fridge that stays shut holds a safe temperature for about four hours. A full freezer holds one for about two days. Here is why the door, not the clock, decides the outcome.
What temperature should a fridge actually be set to?
The number on the dial is not a temperature. Here is the target that matters, and the cheap way to find out whether your fridge is hitting it.
Why does the back of the fridge freeze things?
Frozen food in a fridge is usually a placement and airflow problem, not a fault. Here is what is actually happening at the back wall.
Should you let food cool before putting it in the fridge?
Waiting for food to reach room temperature is the part of the advice that causes problems. The real goal is speed through the danger zone, and there are better ways to get it.
Does a full fridge stay colder than an empty one?
A moderately full fridge holds its temperature better than an empty one. A packed one is worse than either, and for a reason people rarely mention.
Should you wash vegetables before putting them in the fridge?
Wash before you eat, not before you store. The reason is moisture, and it applies to almost everything except the things you are going to use immediately.
How to store leftovers so you actually eat them
The container decides more than the recipe does. Why opaque tubs and large portions are where leftovers go to die, and what to do instead.
