What is the function of baking tin foil in the oven?
Tin foil has the functions of heat preservation, waterproof, sealing and electric conduction. In addition to helping food to be heated evenly in cooking such as barbecue and baking, it can also play the roles of refrigeration, sealing and heat preservation, and isolating heat sources. And it is indispensable for outdoor barbecue.

For example, when baking bread, you can use the most commonly used bread to prevent the bread from burning. For example, when cooking tinned silver cod, you can wrap it with tin foil to gather heat, shorten cooking time and keep the temperature. In addition, some meat dishes are easy to produce oil smoke or burn when cooking, and tin foil can also solve the problem and avoid the generation of harmful substances.

Tin foil is like a mysterious coat, which is wrapped with nutrition and moisture in the ingredients. The tinfoil is cut with a knife and smells good.

Tin foil can be divided into glossy surface and matte surface. The smooth surface can better absorb external heat and help food to be heated evenly. When the matte surface touches the food, the heat can be evenly distributed on the food surface, and the cooking time can be shortened.
