First, because these raw materials have been blanched and almost cooked.
Many people like to eat in restaurants, but what everyone hates most is that restaurants are full of people, and chefs spend a lot of time cooking, so everyone needs to wait in line all the time. However, the chefs in some restaurants cook very fast, so the radio waves delay everyone's dinner, so some people who go to work will come to this restaurant to eat in order to hurry. However, some people are curious. It usually takes more than ten minutes to cook and stir-fry a dish at home, but the food in a restaurant can be cooked in a few minutes. In fact, because the raw materials in these cities are super-watered or fried in advance, these materials are almost cooked, and guests can serve after ordering and heating.
Second, because the fire in the kitchen is relatively large.
People eat in the front hall, of course, they don't often go to the back kitchen. In fact, the kitchen is also very messy, the temperature is relatively high, and the fire in the stove is very big. Therefore, the bigger the fire, the faster the dishes will be cooked, and the chef can cook them well in a short time.
Third, because chefs can cook many dishes at once.
Some chefs cook a lot in advance and then take measures to keep the food warm. Then when the guests order, the chef can directly present the food to the customers. However, this method is not common. If food is cooled and reheated, the taste will change and customers will not buy it.
