- Check for allergies before you begin and read the guidance on food safety. Make sure you have suitable areas for storing and preparing food and avoid cross contamination of different foods.
- Kettles, cookers and microwave ovens produce a lot of heat by the very nature of them. Caution is needed when in contact with items that have been heated and young people should use them under adult supervision. Use on a suitable surface, protecting it if necessary.
