Why should the oven with aluminum foil
Aluminum foil thermal conductivity, high temperature resistance, easy shaping. Clear enough?
1., as a pad of paper on the baking board, used to pad on the baking tray, to avoid direct contact with the food with the baking dish, to prevent food from sticking to the baking pan; and secondly, to isolate the bacteria on the baking board, more hygienic. Besides, the trouble of cleaning the baking pan is avoided. The foil can be repeatedly used, save money.2 when the meat or seafood can use aluminum foil wrap ingredients, prevent moisture loss, keep the food fresh taste! When baking easy to paste food, use it to pack food to prevent burning.3 another magical we bake a cake or bread, in order to keep the surface color too deep, can be in the food after the color on the surface covered with a layer of aluminum foil, so the surface will not be because of color too deep and beautiful ~ (cover when the contents of the action to be fast, avoid the oven temperature change is too big at the same time, careful hot).
The foil is a similar to the paper sheet metal packaging or packaging for carrying food. It is widely used in every field of life. Now we often use home baking in foil already not by tin made, because of the low melting point of tin, 160 degrees will occur brittle, so limiting the application of aluminum foil. In modern process, aluminum foil is used instead of tin, and the melting point of aluminum foil is 660 degrees, so baking or other high temperature heating method can use it, and it is clean and sanitary, and the price is not high. So strictly speaking we use now should be called "foil", rather than "foil"
