electric ovens need to be preheated before baking any ingredients. For example, when we want to bake cakes or cookies, the preheating requirement is 22 degrees. When preheating, the temperature of the electric oven is set at 22 degrees, and then the baking time of the oven is set at 5 minutes.

When the oven has been working for 5 minutes, the temperature inside has reached the predetermined temperature. At this time, you can open the lid of the oven, immediately put in the ingredients you want to bake, and then bake according to the baking time of different ingredients.

why.

First of all, if you start baking at low temperature, the baking time will be prolonged, and the cakes will be too dry after baking, and some will affect the color of the finished products.

Secondly, when the oven door is opened and dough is put in, the temperature of the oven will be greatly reduced instantly, thus affecting the baking time and color development. Therefore, general oven preheating should pay attention to the following points:

1. The preheating temperature should be 1-2℃ higher than the baking set temperature;

2. The preheating time is generally about 1-15 minutes;

3. After the dough is put in, the oven should be reset to the predetermined baking temperature. Baking is a delicate matter, and any small change in the baking process will have an impact on the final result.

Therefore, if you want to bake a good work, you must control the oven temperature accurately. If you feel that the oven temperature is not easy to control, you can buy a thermometer used in the oven.
