Most of us throw away more food than we’d like to admit. A wilted bag of spinach here, a soft punnet of strawberries there — it adds up fast, and with grocery bills where they are right now, it’s money nobody can afford to waste. The good news is that a few small changes to how you store things at home make a real difference.
Store Your Herbs Like a Bunch of Flowers
Fresh herbs are one of the most wasted things in the weekly shop. You buy a bunch of coriander or flat leaf parsley, use a handful, and the rest turns to mush in the fridge within days. The fix is simple — trim the stems, stand them in a glass with a couple of centimetres of water, and put a sandwich bag loosely over the top. They’ll last well over a week like this. If they’re already starting to wilt and you know you won’t get to them in time, chop them up and freeze them in an ice cube tray topped up with water. Drop a cube straight into soups, stews, or sauces when you need them.
Wash Your Berries in Vinegar Before You Store Them
Strawberries, raspberries, and blueberries go off so quickly because berries pick up mould spores during growing and transport, and by the time they’re sitting in your fridge the conditions are perfect for them to take hold. Washing them in a solution of three parts cold water to one part white wine vinegar is widely recommended to deal with this before storage — rinse them well afterwards, dry them thoroughly, and store in a container lined with a sheet of kitchen roll. Rinse them well afterwards, dry them thoroughly — wet berries go off faster — and store them in a container lined with a sheet of kitchen roll. They’ll easily last twice as long in the fridge.
Wrap Banana Stems in Clingfilm
Bananas go brown so quickly because they release ethylene gas from the stems, which speeds up the ripening process across the whole bunch. Wrapping the stems tightly in clingfilm slows the gas down and buys you several extra days. If you’ve got bananas that are already past their best, peel them and freeze them in a bag — they’re perfect for baking or blending into a smoothie straight from frozen.
Run Stale Bread Under the Tap Before You Put It in the Oven
Before you throw out a loaf that’s gone hard, try this. Run it briefly under the cold tap so the outside is damp, then put it in the oven at around 180°C for about ten minutes. The moisture rehydrates the bread as it heats, and it comes out tasting genuinely fresh. It works best with crusty loaves, but it’ll revive a sliced loaf, too. If you know a loaf is going to go stale before you finish it, slice it and put it straight in the freezer — it toasts from frozen in minutes.
Keep Carrots and Celery Submerged in Water
Once carrots and celery are cut, they go limp surprisingly fast in the fridge. Cut them into sticks, stand them upright in a jar or container, and cover them completely with cold water. They stay crunchy for up to two weeks like this. Change the water every few days, and they’ll keep even longer. It’s worth doing this straight after your shop, so they’re ready to grab when you need them.
Wrap Cheese in Baking Paper, Not Clingfilm
Cheese needs to breathe, and clingfilm doesn’t let it. Wrapping it tightly in plastic traps moisture, which is what causes it to sweat and go slimy. Swap to baking paper or greaseproof paper instead — it lets the cheese breathe while still protecting it from drying out completely. Hard cheeses like Cheddar and Red Leicester last significantly longer wrapped this way. If you’ve got a rind starting to harden on the cut edge, just trim it off before eating.
Freeze Leftover Wine in an Ice Cube Tray
If you’ve got half a bottle of wine left and you’re not going to finish it, don’t pour it down the sink. Freeze it in an ice cube tray and transfer the cubes to a freezer bag once they’re solid. They’re ideal for adding to a bolognese, a casserole, or a gravy. It won’t be worth drinking on its own once it’s been frozen, but for cooking, it’s perfect, and it means nothing goes to waste.
Keep Potatoes in the Dark
Potatoes go green and start to sprout when they’re exposed to light, and both are signs the potato is producing solanine — a compound that makes them taste bitter and can cause stomach issues in large amounts. Keep them in a dark cupboard or a paper bag away from any light source. Don’t store them in the fridge either — the cold converts the starch to sugar and changes the texture and taste.
Never Store Potatoes Next to Onions
Both potatoes and onions release gases that cause each other to deteriorate faster. Store them in separate dark, well-ventilated spots, and both will last considerably longer. Garlic can go with the onions, but potatoes are better off on their own.
Store Apples Away From Everything Else
Apples are one of the biggest ethylene gas producers in the fruit bowl, which means they speed up the ripening — and rotting — of everything around them. Keep them in a separate bowl or in the fridge,e and your other fruit will last noticeably longer.
Freeze Fruit Before It Turns
If you’ve got fruit that’s perfectly ripe but you know you won’t eat it in the next day or two, freeze it. Berries freeze well spread out on a tray first, so they don’t clump together. Bananas, mango, pineapple, and grapes all freeze well and work brilliantly in smoothies, overnight oats, or baking. It takes two minutes and saves you from throwing it in the bin later in the week.
Line Your Salad Container With Kitchen Roll
Bagged salad and loose leaves go soggy because of the moisture that builds up around them. Take them out of the bag, line a plastic container with a sheet of kitchen roll, put the leaves in, and lay another sheet on top before sealing. The kitchen roll absorbs the excess moisture, and the leaves stay crisp for days longer than they would in the original bag.
Keep Avocados in the Fridge Until Two Days Before You Need Them
The mistake most people make with avocados is leaving them on the counter and then missing the thirty-minute window when they’re actually ready to eat. Buy them firm and keep them in the fridge — the cold slows the ripening right down. When you want to eat one in the next day or two, move it to the counter and let it ripen at room temperature. If you’ve cut into only used half, leave the stone in the unused half, squeeze a little lemon juice over it, and wrap it tightly — it’ll keep in the fridge for another day without going brown.
Freeze Bread Before It Goes Stale
If you’re not going to get through a loaf before it starts to go, put it in the freezer as soon as you buy it, rather than waiting until it’s almost past it. Sliced bread toasts directly from frozen in a toaster at the same time as it would from fresh. For rolls or crusty loaves, give them ten minutes in a warm oven, and they’ll be good as new. It’s one of the simplest ways to stop bread waste entirely.
Put a Sheet of Kitchen Roll in Your Bag of Spinach or Greens
Spinach and other soft greens go slimy because of moisture build-up in the bag. Open the bag, tuck a sheet of kitchen roll inside, and reseal it. The paper absorbs the excess moisture,e and your greens will stay usable for days longer. Replace the kitchen roll if it gets very damp.
Freeze Milk Before the Use-By Date
Milk freezes well, ll and most people don’t realise it. If you’ve bought a big four-pint bottle and you know you won’t get through it in time, pour some into a freezer-safe container — leaving room at the top for expansion — and freeze it. It’ll keep for up to three months. Move it to the fridge the night before you need it and give it a good shake once it’s defrosted, as it can separate slightly, but the taste is completely unaffected.
