Why is the crucian carp soup in the restaurant so white?

Tofu or milk may be added to the crucian carp soup in the hotel. First, fry a crucian carp until both sides are slightly yellow. The second is to add freshly boiled water to ensure that the water will be out of the pot immediately. Third, fish soup should be cooked in medium heat, and the soup should be cooked for about ten minutes. Only when it is boiled will it be white. You can also add soybean oil. You can cook any soup with soybean oil, but the vegetarian soup is not strong and the meat soup is very strong.

The first step of frying fish is also exquisite. First, put the main fish in a pot and fry it until both sides are golden, then put it in a pot and cook it. When frying fish in this way, the oil is brought into the soup, and the protein content of the fish itself is also very rich. In order to prevent the pan from sticking, first heat the pan to the point of smoking, and then fry it immediately, or directly fry it with pigs. There is only one thing to pay attention to in the soup-making stage, and that is the heat. Be sure to choose fire to make water boil, so that oil and water can be fully emulsified under the action of protein. The longer the cooking time, the more pleasing the color of the fish soup.

Crucian carp soup and preserved egg and winter melon soup are both white, because the raw materials of these soups are rich in protein and fat. Some people say that lard should be added to soup white because lard is white, but it is not. When the fish is small, it is recommended to add a little lard. Because fish contains less fat and protein.

The color of soup is like milk, and it is emulsified mainly by protein. Fire is also a key to making milk soup. Because of boiling, oil and water are fully emulsified under the action of protein, which makes the soup look like milk. Some people say that milk will be added to the kitchen to make the soup white. In fact, the main purpose of adding milk is to increase protein. Otherwise, if you want to make Tonga white, how much milk tastes.
