How do I keep aluminum foil facing from sticking to itself?

To prevent aluminum foil from sticking to itself, you can try several methods. First, store it with a sheet of wax or parchment paper between each layer to create a barrier. Second, lightly coat the foil with cooking spray or oil before stacking. Alternatively, use a paper towel as a separator. When using, dampen the foil slightly with water to reduce the sticking. Additionally, you can purchase non-stick aluminum foil or use plastic wrap as a substitute. These methods will help maintain the separation and functionality of aluminum foil.
