Quick answer
Cool food intended for later use as quickly as possible using a suitable, checked method, then refrigerate it safely. Smaller portions, shallow containers and appropriate chilling equipment can help. The correct method depends on the food, depth, batch size and equipment; one time limit cannot safely describe every commercial process.
Cooking is followed by another important control
A thoroughly cooked dish can become unsafe if it cools slowly or becomes contaminated afterwards. Large dense batches are especially difficult to chill uniformly.
The SFBB cooling method advises prompt chilling, sensible batch size and checks of the actual method. CookSafe provides the Scottish catering approach.
Choose a method that fits the food
| Issue | Useful option or check |
|---|---|
| Large quantity | Avoid unnecessary advance production; divide suitable food into smaller amounts. |
| Deep container | Use a suitable shallower arrangement that lets heat escape. |
| Liquid dish | Consider safe stirring and appropriate cold-water or ice arrangements. |
| Repeated bulk production | Assess properly specified blast-chilling capacity. |
| Contamination | Protect food and use clean equipment throughout cooling. |
| Refrigeration load | Avoid warming other stored food with an unsuitable hot load. |
These are options to assess, not a recipe interchangeable between all dishes. Check equipment instructions and the food-safety method before choosing how a hot batch enters refrigerated storage.
Check performance before relying on the method
Record the food, batch quantity, container depth, equipment and cooling arrangement. Use a clean suitable probe and timed checks to understand how the representative food cools, following the official “prove it” approach.
Set safe operating criteria with appropriate guidance and competent advice. Check the slower-cooling part, not just a thin edge. If the batch, recipe or equipment changes, establish whether the evidence still applies.
Worked example: the same recipe in a deeper pan
Hypothetical example: a kitchen doubles a soup batch and leaves it in one deep vessel, assuming the usual process still works. A surface check does not establish how the centre is cooling.
The supervisor uses the agreed method for manageable portions and checks its performance. The production plan is revised so the available equipment can handle the quantity, rather than asking staff to sign the old cooling record.
If cooling has not followed the safe method
Stop the affected food from being served and establish its temperature and time history. Follow the food-specific corrective procedure and seek advice when suitability is uncertain. Do not assume reheating removes every consequence of slow cooling: rice is a particular concern in FSA guidance.
Record what happened and the food decision. Correct batch size, equipment capacity, timing or supervision before repeating the process.
Common cooling mistakes
- Leaving a bulk pan overnight because it has a lid.
- Using one number as universal UK cooling law.
- Checking a shallow surface instead of the representative food.
- Moving hot food into storage that cannot handle the load.
- Assuming every failed batch can be rescued by reheating.
Next steps
Write down the actual method and demonstrate that it works at the intended scale. Use clear monitoring and corrective-action records and refrigerated-storage checks.
