In these cold areas, food is cooked from the kitchen and moved to the table for a period of time. Especially in cold weather, food will soon get cold on the table. If the colded food is heated in the oven, it will dry out due to overheating and evaporation of water, which will affect the taste of the food. In particular, all kinds of mites, such as burdock and mutton, are more obvious. The colder these oysters are, the worse they are. If you can eat hot food from the beginning of the meal to the end of the meal, food (and dishes such as dishes) can always stay in the temperature range of 55 Ό to 6 CTC, then the taste of the food will not change the texture and taste due to temperature changes. The diners will be able to enjoy a perfect lunch/dinner, and they will be able to eat more and better, and the family life will be perfected.
