1. The oven must be preheated when used. If you put the food directly into the oven without preheating, the heating pipe will be fully heated at this time, and the food will face problems such as uneven heating, water loss, and easy burning of the surface, which will affect the quality. Pay attention to the condition of the heating pipe. When the heating tube turns from red to black, it means that preheating is completed. Theoretically, the higher the power, the faster the oven heats up. Generally, preheating takes 5- 10 minutes.

.2. For those household ovens that can't adjust the temperature of the upper and lower tubes separately, when encountering a formula that requires different temperatures of the upper and lower tubes, such as "oven middle layer, upper tube 180 degrees, lower tube 200 degrees", we can take the average value and heat it, and put the baking tray on the next floor.

3. When baking according to the formula, we adjust it flexibly. If you bake cookies at 200 degrees 15 minutes according to the recipe, you should understand that you should lower the temperature or shorten the time next time.

The oven is heated by heating pipes, and the temperature difference between the center and the surrounding area is very large. There are several ways to improve the uneven heating, such as taking out the baking tray in the middle of baking and putting it back in the other direction. Or change the food in the baking tray. Cover the surface of food with a layer of tin foil and so on. The bigger the oven, the lighter the uneven heating.

5. After each use, the electric oven should be wiped clean after cooling. The baking tray and baking net can be cleaned with water, but the oven door, cavity and shell can't be cleaned with water, and they should be wiped with a dry cloth. When the oven cavity, baking tray and baking net are baked with carbonized food juice and it is difficult to clean, the cuttlefish bone can be dipped in water or gently wiped off with detergent.

I hope I can help you and adopt it. Thank you!
