Tinned beans, tomatoes, fish and fruit are dependable, affordable ingredients when cans are stored in a cool dry place and remain intact. Check for bulging, leaking, severe rust or damage around seams, and discard anything suspicious without tasting it.
Rinsing beans can reduce some surface salt and improve flavour or texture; it is not required to make an undamaged commercial tin safe. Once opened, transfer unused food to a covered container and refrigerate it.
Rotate older tins forwards and use them in normal meals rather than saving them indefinitely. Their strength is reliable food ready when fresh plans change.
Why rinse beans and chickpeas
Draining and rinsing beans or chickpeas can reduce some sodium and remove the thicker packing liquid. It may also give a cleaner flavour in salads and savoury dishes.
Aquafaba can be saved for cooking when the tin and salt level are suitable, but refrigerate it promptly and use it safely.
Inspect every tin before you open
Do not use tins that are bulging, leaking, badly rusted or deeply dented around a seam. Discard food that spurts, smells abnormal or looks unsafe when opened without tasting it.
Do not taste suspicious canned food
A damaged or bulging tin is not worth testing. Dispose of it safely and use another product.
Bulging or leaking - discard unopened; don't taste.
Deep dents at the seam or rim - discard; micro-holes are possible.
Rust through the metal - discard.
Store in a cool, dry cupboard, not above the boiler or in direct sun.
Transfer unused contents to a clean covered container, refrigerate them and follow the label for timing. Write the opening date on the lid if useful.
This also makes it easier to give the ingredient a clear second meal.
Soft edible bones in sardines and pilchards provide calcium. Mash them into toast toppings, pasta or fish cakes if the texture is unfamiliar.
Choose fish in water, brine, tomato or oil according to taste and nutritional needs.
Tinned tomatoes and pulses create quick soups, curries and sauces. Compare the unit price because a multipack is not always the cheapest option.
Buy amounts that fit storage and the meals you actually cook.
Tins make a fast start for chilli, soup and curry. Cool extra portions promptly, freeze in useful amounts and reheat safely.
Convenience at the beginning does not change the usual rules for leftovers.
After the tin is opened
Transfer unused contents to a clean covered container, refrigerate them and follow the label for timing. Write the date on the lid if you are unlikely to remember. Fish, beans and tomatoes can then be given a named second use rather than remaining anonymous.
Do not keep food in an opened tin for convenience, and never taste from a container that is bulging, leaking or spurts unexpectedly when opened. When the package itself raises concern, the economical decision is to discard it.
