Is it safe to wrap food in aluminum foil before baking it? It's hard to clean the baking sheet from the stains left by baking food. I was wondering if it is safe to bake the food wrapped in aluminum foil, or whether some aluminum may be leached into the food?
Not only is it safe but there are entire collections of recipes developed around "foil pack" cooking. Mostly centered around 'campfire' cooking, where one prepares all of the ingredients, wraps them tightly in aluminum foil and places the whole pack in the fire (or oven) to cook the dish.
