Can I use aluminum foil to wrap a cake?

Yes, you can use aluminum foil to wrap a cake. It's a common practice to cover cakes with aluminum foil to protect them from air exposure, which can dry out the cake. It also helps to keep the cake fresh and moist. However, ensure the foil is food-grade and clean before use. Avoid using it for a long period as it may affect the taste and texture of the cake. For best results, consider using plastic wrap or a cake dome, which are specifically designed for food storage.
