In daily life, aluminum foil is a good helper in the kitchen. It has a wide range of uses. Whether it is baking, grilling, or food preservation, it can play an important role.
Baking with aluminum foil can help us solve many problems. For example, when making toast, evenly spread a thin layer of aluminum foil on the baking tray, which can not only help keep the air circulating and prevent the bread from being too dry or too wet, but also protect the baking tray from high temperature damage. When making cakes, you can also spread aluminum foil on the bottom and around the mold, so that the cake is easier to demold after baking, and cleaning the mold becomes much easier.
The steps are as follows: Preheat the oven to the appropriate temperature, like a normal oven, to 180°C. Then spread the aluminum foil evenly on the baking tray, making sure there are no creases to avoid affecting uniform heating. Then place the prepared ingredients on the aluminum foil, leaving a certain gap between the ingredients to avoid overlapping and affecting heat conduction. Finally, put it in the middle layer of the oven and adjust the baking time according to the type and thickness of the ingredients. For example, a small cake may take about 20 minutes, while a large bread may take 30-40 minutes.
Aluminum foil is also indispensable in barbecue. Using the function of metal heat conduction, aluminum foil for barbecue can help heat energy spread evenly into food and speed up the time it takes for food to cook. Moreover, the front and back sides of aluminum foil have different functions. The bright side uses the principle of reflection to isolate heat radiation, while the matte side absorbs heat energy.
When grilling meat, because it is far from the heat source, mainly heat radiation, so the matte side should be facing outward, so that it can better absorb heat and make the meat cooked faster; and when insulating, the bright side should be facing outward. For example, if you want to keep the food temperature for a short time after grilling, you can wrap the food with the bright side facing outward.
Never drop acidic substances such as lemon juice into aluminum foil, because aluminum foil is a metal, and the mixture of metal and acidic substances will undergo chemical changes, which may produce substances harmful to the human body.
Aluminum foil has good oxygen barrier, water barrier and light shielding properties, which can effectively block the entry of air, moisture and light, thereby reducing the contact between food and the external environment and delaying the oxidation, deterioration and corruption of food. Whether it is fresh meat, fish, poultry, or various vegetables and fruits, they can be wrapped in aluminum foil for preservation.
Many people worry about whether it is safe to use household aluminum foil. In fact, qualified household aluminum foil is safe under normal use. Food-grade aluminum foil is specially designed and produced for contact with food. Its production process strictly follows relevant standards and specifications. There is an oxide film on the surface, which can play a protective role and prevent the large amount of aluminum from migrating into the food.
