What properties make aluminum foil useful for baking?

Aluminum foil is useful for baking due to its heat conductivity, which allows for even cooking and browning of food. Its ability to reflect heat helps maintain optimal temperatures, preventing over-browning or drying out. Additionally, aluminum foil is versatile, serving as a barrier to keep moisture in or out, and can be molded to fit various shapes, making it ideal for lining pans or wrapping food. Its lightweight and disposable nature also simplifies cleanup.
