Oil paper is usually placed under the oven to prevent food from sticking, which is more suitable for making desserts such as bread. If it's barbecue food, wrap it in aluminum foil.
If you don't use tin foil, you can also brush a layer of oil or sprinkle a layer of powder on the baking tray with a brush, so that it won't stick when baking again. Observe the color of the meat when baking, and turn off the fire immediately after discovering discoloration to avoid burning.
The function of tin foil is to transfer heat quickly and radiate evenly, which will not scorch food, and can also prevent the oil baked by food from polluting the box. At the same time, the food wrapped in tin foil can also reduce the loss of nutrition and water, so tin foil is a better choice when baking food.
