If the oven is not preheated, it can also be baked directly, but it will take longer, and the baked finished products will be small and hard, but they can still be eaten normally. The oven is preheated before baking, which can heat the temperature to the temperature required for baking food and ensure the taste of food. How to solve the problem that the oven is not preheated? Preheating refers to pre heating to the specified temperature. Its main purpose is to prevent rapid heating and preheat the materials before formal baking. Now basically, no oven has a special 'preheating' function key. It mainly depends on how people use it, and preheating is an important action in baking.
In fact, if the oven starts baking directly without preheating, the food can also be baked, but it will take longer, and the baked finished products will also have the disadvantages of small size and hard taste, but it will not affect normal food use.
Generally speaking, the oven needs to be preheated when baking things, and the time will not be too long. Basically, it can take about 10 minutes. If the preheating time is short, it can not reach the temperature required for baking, and the effect of finished products is not good. If the preheating time is long, it will affect the service life of the oven, so we must pay special attention.
