A good electric oven can bake in layers at the same time, but generally speaking, most household electric ovens can't bake at the same time, and can only bake in a single layer, because layered baking needs the relationship between fire and fire, and it is easy to bake to one side. Even if the electric oven has the function of hot circulating air, it can't bake two layers of food at the same time. But some professional ovens can adjust the temperature of the upper and lower tubes separately.

When baking in the oven, you can also choose the position according to your favorite taste, some like to burn, and some like to be tender. If you need to bake faster colored dishes, it is recommended to put them in the middle and upper layers, such as chicken wings, steaks and other meat. If you need to bake recipes with slow coloring, it is recommended to put them on the lower floor, such as almond cakes, cakes, bread and other western pastry. Other dishes are generally recommended to be placed in the middle layer.
