Common questions
How long does frosting or icing last in the fridge?
2–3 weeks in a fridge running at 0–5°C (USDA FoodKeeper guidance). After that, quality and safety both start to slip, and because the bacteria that cause food poisoning are invisible, ‘it seems fine’ is not a reliable test. When in doubt, throw it out.
How can I tell if frosting or icing has gone off?
Fuzzy white, green or black spots mean mould. Its threads spread through soft, porous foods, so discard the whole item rather than cutting the spot out. Do not rely on this alone: the time guideline matters even when everything looks fine.
Can I freeze frosting or icing to keep it longer?
Freezing is not recommended for this food; the texture tends to suffer badly. Buy or cook only what you will use in time.
Can I keep frosting or icing out of the fridge?
Yes, for a short time only: around 10–12 months in the cupboard or at room temperature.
