Yes, you can use aluminum foil facing to line a baking pan for baking. The shiny side of the foil, which is the aluminum side, is safe for direct contact with food and can be used to line pans for baking. It helps prevent food from sticking and makes cleanup easier. However, ensure the foil is heavy-duty to withstand high temperatures and does not tear easily. Always follow the manufacturer's guidelines for safe use and avoid overheating, as aluminum foil can melt at very high temperatures.
