Can aluminum foil be used to make food?

Yes, aluminum foil can be used to cook food. It's commonly used for wrapping, covering, or lining pans to prevent food from sticking and to retain moisture. Aluminum foil is also used for making packets or pouches to steam or bake food, known as 'en papillote'. However, it's important to note that aluminum foil should not be used with acidic foods or at high heat for extended periods, as this can lead to the foil breaking down and potentially releasing aluminum into the food. Always follow the manufacturer's guidelines and use aluminum foil as recommended for cooking.
