A well-run pantry has less to do with matching jars than with knowing what is in them. If you are starting with an empty cupboard, or one filled with half-used packets you never look at, begin small. Ten British staples, stored properly, will cover most weeknight cooking: a pasta bake, a chilli, porridge, a tray of scones, a decent cup of tea. Once those ten are working, the rest is easy.

Start with ten, not fifty

New pantry keepers usually overbuy. A trolley full of specialist ingredients feels productive, but it often ends up as a shelf of things you never reach for. The useful question is not "what should a pantry contain?" but "what do I actually cook?"

Write down the meals you make most weeks — spaghetti bolognese, a bean chilli, porridge, a roast on Sunday. The ingredients they share are your starting list. Buy those in sizes you will finish within a few months, and let the pantry grow out of your cooking rather than out of a list you found online.

Buy what you cook, store what you buy, and use what you store. That loop is the whole job.

The ten staples worth starting with

These ten cover a surprising amount of ground. Quantities are up to you; the notes are about keeping them in good condition.

1. Plain flour. A 1kg bag handles sauces, shortcrust and scones. White flour keeps longer than wholemeal, which contains more oils. Keep it airtight, cool and dark.
2. Caster sugar. Dissolves easily in baking and sweetens drinks. It hardens when it takes in damp air, so a lidded jar matters more than the brand.
3. Dried pasta. Two shapes to begin with — penne and spaghetti will do. The cooking instructions on the packet are worth keeping even if you decant the pasta.
4. Rice. Basmati or long-grain, whichever you eat. Rice needs the driest shelf you have and a properly sealed container.
5. Chopped tomatoes. Tins stack neatly, keep for a long time and form the base of countless sauces and stews. Buy them in multiples.
6. Tinned pulses. Chickpeas, kidney beans, butter beans. Cheap, filling and ready in minutes, which is exactly what a pantry is for.
7. Stock cubes or bouillon powder. The difference between a thin sauce and a good one. They clump badly in steam, so keep them away from the kettle.
8. Porridge oats. Breakfast, crumble topping, flapjacks. Oats go stale and slightly bitter over time, so buy a bag you will use within a couple of months.
9. Tea and coffee. Whatever you drink daily. Tea picks up the smell of anything nearby, so give it its own jar away from spices.
10. Salt, pepper and one everyday oil. Rapeseed or olive oil, plus a grinder of black pepper. Add malt vinegar or balsamic when you find you keep reaching for it.

How to store them so they last

The container question

You do not need a full set of new jars. Airtight is the only rule that matters, and clip-top glass jars, screw-lid jars and plastic tubs with silicone seals all do the job. Clear containers are better than opaque ones because you can see what is left without opening anything.

Decant only what you will use in a reasonable time. If you tip flour into a jar, cut the best-before date off the bag and tape it to the lid, or write it on a label. That small habit stops a shelf of anonymous white powders building up.

Where in the cupboard

Heat, light and damp are the three things that shorten shelf life. Keep dry goods away from the oven, the radiator, the dishwasher and the kettle. A high shelf above a boiling pan is the worst place for flour, oats and stock cubes.

Tins like cool and dry, and they should be used before any dents turn rusty. Once a tin is opened, transfer what is left to a lidded tub and put it in the fridge — a half tin of tomatoes left in the tin in the cupboard will not do you any favours.

The rotation habit

New stock goes to the back, older stock comes to the front. It takes ten seconds and it prevents the quiet waste of buying a third bag of rice while the second one sits forgotten. Keep a "use me first" basket at eye level for open packets and anything close to its date.

A running list on the inside of the cupboard door, or a note on your phone, is enough. Add to it when you finish something rather than when you shop, so the list reflects what you genuinely use.

Five beginner mistakes to avoid

• Buying in bulk without the space. A 10kg sack of rice is only good value if you can store it cool, dry and sealed.
• Leaving flour in its paper bag. It splits, absorbs smells and invites pests. Decant it or clip the bag inside a larger tub.
• Storing onions and potatoes together. They keep each other going over — one sprouts, the other softens. Keep both out of the dry goods cupboard altogether.
• Ignoring the first moth. If you spot webbing or tiny moths in a packet, bin it in the outside bin, then wash the shelf with hot soapy water and let it dry completely before restocking. Check neighbouring packets too.
• Filling jars you cannot see into. If you cannot tell what is in a container at a glance, you will buy it again.

Your first week: a simple plan

Choose three meals you cook regularly and list their ingredients. Buy only those, plus the ten staples above, and put them away the same day rather than leaving bags on the worktop. Wipe the shelf first, check the dates on anything you already own, and move the older items forward.

Then set a ten-minute slot once a week — Sunday evening works for most people — to look at what is open, what is nearly finished and what needs adding to the list. That is the loop: cook, use, replace, repeat. Within a month you will know your pantry well enough to cook dinner without a shopping trip, which is the point of having one at all.
