Read food labels before you cook

The front of the packet is only the introduction

A product name tells you roughly what is inside. The useful cooking instructions are often on the back or side, with the date stamped on a lid or seal. Turn the package over before opening it. Keep it beside the recipe until you have checked the ingredients and storage instructions, then keep it away from raw-food splashes.

Use one item you already have for this practice, such as a stock cube, canned beans or a sauce jar. You need its original packaging, enough light to read small print and somewhere to note the opening date. There is no need to taste the food to complete a label check.

Make five checks in order

1. Identify the exact food and form. Is it dried, ready-cooked, concentrated, chilled or frozen? A recipe asking for 250 ml made-up stock does not mean 250 ml concentrate. A pack of dried beans is not a substitute you can use like an opened can.
2. Find the full ingredients list and any separate allergy warning. Read the whole list, including ingredients inside brackets for a sauce or seasoning. Check every new pack; familiar products can change.
3. Find whether the date says use by or best before, and read any wording beside it. Look where the pack says the date is printed. If you cannot read it on a food whose safe use depends on it, do not guess.
4. Read storage before and after opening. A shelf-stable carton may need the fridge after opening. Write the opening date on the pack or a label when a short after-opening period applies.
5. Read preparation from beginning to end. Notice whether instructions start from frozen or chilled, whether rinsing is needed, and whether cooking, stirring or standing time is required. Follow those instructions rather than assuming all products with the same name are interchangeable.

Use by and best before answer different questions

A use-by date concerns safety: do not eat food beyond it just because its smell seems normal. Food cooked or frozen on or before that date is a separate case with its own storage limits, explained in the storage lesson. A best-before date mainly concerns quality. Correct storage still matters, and a damaged package or spoiled food is not made acceptable by an unexpired date. Follow any shorter after-opening limit.

For example, if a refrigerated item is opened on Monday, says use within two days, and has a use-by date on Tuesday, Tuesday remains the earlier limit. Freezing on or before a use-by date can be an option when the food and packaging instructions permit it; freezing is not a rescue for food already unsafe. Use the storage lesson to plan cooling, freezing and defrosting rather than just changing a date.

Allergens need a separate decision

• UK labels highlight specified allergen groups in the ingredients list, often in bold. These include milk, egg, fish, crustaceans, molluscs, peanuts, specified tree nuts, cereals containing gluten, soya, sesame, mustard, celery, lupin and sulphur dioxide or sulphites above the labelling threshold. People can react to foods outside these groups too.
• A may-contain warning concerns possible unintended presence. It is not the same as an ingredient, but is not permission to ignore the risk. Ask the person eating what they can safely have and follow their established requirements.
• Vegan does not mean free from allergens. A product can contain soya, wheat or nuts, or have a warning about milk or egg contamination.
• An absent or unclear label is not evidence that a food is suitable. Keep the packaging available and ask the manufacturer or choose an ingredient with verifiable information if needed. Do not serve a doubtful product and ask the person to try a little.

Keep suitable food suitable during preparation

• Clean and set up your kitchen before cookingSet up clean equipment and separate preparation areas.

If cooking for someone with an allergy, agree the ingredients with them before starting. Clean hands, surfaces and equipment thoroughly, use clean cloths, and prevent crumbs, shared utensils and splashes from other ingredients reaching their food. Removing a visible piece or cooking a food longer does not reliably remove an allergen.

Make a separate plan when you cannot confidently prevent unwanted contact. A home lesson cannot certify your kitchen or a meal as allergen-free. The useful outcome is a clear decision about what you can safely prepare, not a confident-sounding guess.

Finish the practice before opening

• Storage and reheating basicsApply the relevant cooling, fridge and defrosting limits.

Explain your chosen product in one sentence: what it is, how it is prepared, where it goes after opening and when you must use it. Check suitability with anyone you are feeding. If any of those answers is missing, resolve that point first.

Keep the cooking directions until the meal is finished. When transferring food to another container, retain its identity, date and important allergen information; an unlabelled white powder is not a useful pantry system.
