Can aluminum foil facing be used for cooking? If so, what types of food can it be used for?

Yes, aluminum foil can be used for cooking, but it's important to use it safely. It's suitable for wrapping foods like fish, meats, and vegetables to retain moisture and flavor. It's also used for making packets for steaming or baking, and for lining baking sheets to prevent sticking. However, avoid using it with acidic foods or at high temperatures as it can react with the food or release aluminum into the food. Always use heavy-duty aluminum foil for cooking to ensure it can withstand the heat.
