It has the characteristics of long history, exquisite craftsmanship, rich categories, numerous schools and unique style. It is the crystallization of thousands of years' development of China cuisine and enjoys a high reputation in the world. China cooking is an important part of China culture. Also known as China food culture. One of the three major cuisines in the world (Chinese cuisine, French cuisine and Turkish cuisine) has a far-reaching influence on East Asia. The menu comes from dishes of various regions and nationalities in China. Summarized as: color, fragrance, taste, meaning and shape. Known as the five major cuisines. Chinese food has many characteristics. Compared with other countries in terms of cooking culture, Chinese food is more colorful, exquisite and beautiful, harmonious and moderate. Cooking characteristics can be divided into four aspects: material selection, knife work, heat and seasoning. Chinese food is very rich in ingredients. There is a saying: "wild animals in the mountains fly in the clouds, and cattle and sheep on land are fresh at the bottom of the sea." Almost everything that can be eaten can be used as ingredients in Chinese food. But the choice of ingredients is related to the quality of dishes. Famous dishes in China often use precious ingredients, such as bird's nest, shark's fin, bear's paw, deer's tail, tiger bone and monkey brain. Some ingredients come from protecting animals, so some famous dishes can't be made because of the difficulty in obtaining materials. However, some chefs try to use substitutes in the right season: the quality of ingredients varies according to the maturity time of animals and plants. For example, Huaiyang cuisine has a saying that "swordfish is unclear, sturgeon is not the Dragon Boat Festival". The selection area of ingredients is suitable: the quality of ingredients grown in different regions is also different. Such as crabs, the above seafood is better. However, due to the development of modern science and technology, regional differences have become less important. Different varieties: Cooking some dishes requires different kinds of ingredients. Beijing roast duck, for example, is made of Beijing's unique stuffed duck; Boiled chicken is made of Sanhuang chicken. This kind of chicken is said to be castrated when it is young and fed with a certain amount of peanuts. Part difference: different parts of the ingredients are made into different dishes. For example, the "meat segment" of home cooking is tenderloin. Fresh and tender: Almost all Chinese dishes require fresh ingredients, such as "small fried pork", which requires pork tenderloin to be taken after the pig is killed alive, so as to make the ingredients fresh and delicious. Changes with the times: for example, Beijing roast duck used to be as fat as possible, but now it tends to use lean duck. No longer use protected animals and precious plants as ingredients. Expand the utilization of insects and introduce other food sources, such as expanding the consumption of scorpions and locusts and introducing French snails. Five colors of ingredients: Some ingredients are used to decorate colors. For example, add a little saffron to shark fin soup. Note that in Chinese food, anything decorated must be edible. Incense: some ingredients used to add flavor. In fact, some spices such as pepper and fennel are mainly used for seasoning to remove the fishy smell, bad smell or peculiar smell of ingredients. There are also some high-class dishes, such as lotus leaf wrapped beggar chicken, which smells delicious. Flowers are added to the flower cake and it tastes like a garden. Taste: The choice of ingredients can also improve the taste of food. For example, shrimp brains added to shrimp dumplings. Make jiaozi more delicious. Meaning: The name and shape of ingredients can represent the artistic conception of dishes. In ancient times, examiners had to eat a red carp when they rushed for the exam, which meant yue longmen, a carp. Shape: If it is a cold dish, the requirements for ingredients are also very important. Some ingredients are rich in nutritional value, and some are medicinal. Such as red dates and pig's hand soup. The ingredients are rich in animal glue, which is very helpful for pregnant women.
