A, oven preheating how long
1, we bake food before, food has been in the conditions of room temperature, usually in the food baking when it is baking temperature is more than a hundred degrees or two hundred degrees, if the food in the baking of the oven before the full preheating, but the food directly in the oven, then the equivalent of letting the food from the state of room temperature Heating to the state of baking, if the oven is preheated before baking, then baking food is to let the food directly into the state of baking, different baking methods, the internal organization of food changes are different.
2, generally according to the recipe requirements to the appropriate temperature, let the oven empty for a while, when the interior of the oven to reach a specific temperature and then put the food for baking.
3, the time of preheating: domestic ovens generally do not have preheating indicator. Therefore, you need to pay attention to observe the heating tube, when the heating tube from red to black, it means preheating. According to the temperature, the size of the oven is different, preheating time is not the same, theoretically, the higher the power, the smaller the size of the oven preheating faster.
4, general preheating takes 5-10 minutes. Preheating time should not be too long, if the oven is empty for too long, not only waste of energy, but also shorten the life of the oven.
Second, the use of the oven skills
1, before use to odor. Before using the oven, wipe the oven inside and outside with a clean cloth, open the oven door halfway and then open the upper and lower fires, adjust the temperature to the higher temperature of the oven and bake for 15 minutes, after which it can be used normally.
2. Preheating the oven. Before baking any food, the oven should be preheated, so that the baked food will be more delicious. Usually, the oven can be preheated for 5-10 minutes, preheating temperature lower are required 160 ℃.
3, the baking dish moderate amount of water. In order to avoid baking out of the food is too dry, too hard, better preservation of food in the nutrients, can be moderate baking disk with some water.
4, to prevent the food grilled. Barbecue process is prone to skin overcooked and the internal situation is not cooked, then you can cover a layer of aluminum foil on the food.
5, baking cake oil should not be too much. Bake cake, oil and egg ratio is better for 1:10 (for example: 100 grams of eggs 10 grams of oil,), oil and egg ratio exceeds 1:3, baked out of the cake is easy to deformation.
6, bake the cake temperature control. When baking a cake, the larger the volume of the cake, the lower the temperature required for baking, the longer the baking time; the smaller the volume of the cake, the higher the temperature required for baking, the shorter the baking time.
The above is how long we introduced the oven preheating and oven tips, the oven can make a lot of food, such as cakes, barbecue, cookies, etc., so more understanding of some of the skills of the oven is necessary, so that not only to do out of the food is more tasty, but also to extend the life of the oven.
