Using aluminum foil facing to make a pie crust or tart crust is not recommended. Aluminum foil is not designed for baking and can react with acidic foods, potentially releasing harmful substances. Additionally, it won't provide the same texture or structure as a traditional pie crust. Instead, use materials specifically designed for baking, such as pie dough, tart shells, or parchment paper, which are safe and designed to withstand high temperatures without compromising the taste or quality of your baked goods.
