Tin has only a thin layer, usually less than 0.2mm thick, but it has strong heat conductivity and high temperature resistance. When it is used to wrap food, it can not only be heated quickly, prevent scorching, be heated evenly and easily lock the soup, and keep fresh and tender taste, but also avoid oil stains on the oven.

After being covered with tin foil, there is no fear that the bread or cookies will be too dark in color, so that the heat radiation on the surface of the cake will be uniform, the cracking phenomenon on the surface will be reduced, and at the same time, the food will be baked.
2. Friends who often roast meat can use it to wrap meat for roasting, so that the roasted meat is fresh and tender, and the water content is sufficient.
3. You can also wrap the movable bottom mold into a solid bottom mold with tin foil, so that you can bake in water bath without buying a solid bottom mold.
Correct use of tin:
1. One side of tin foil is bright and the other side is matte. Because the matte surface reflects less light and absorbs more heat outward, you should wrap the food with the matte surface to touch the food, while the bright surface is exposed.
If you accidentally use it backwards, the bright side touches the food, which may cause the food to stick to the tin foil.
2. Try to avoid contact with acidic and alkaline seasonings or foods.
For example: vinegar, lemon, baking soda, etc., so as to avoid chemical reaction and generate aluminum salt; Because this aluminum salt can be absorbed by human body.
3. It's best to rinse it with clear water before use, so as to avoid eating small scraps from the processing process on the tin foil into your stomach.
