It's better to cook fish in cold water when cooking at home. When you use hot water to cook fish, the protein on the surface of the fish will solidify and denature rapidly, but the inside of the fish has not reached the denaturation temperature, and the speed of internal and external denaturation is too different, so the freshness of the fish stew will be reduced a lot, so it is best to use cold water to cook the fish. In addition, if you want to add water in the middle of the stew, you must add boiled water, not cold water.
 1、 Do you use cold or hot water to stew fish at home
 Fish soup is a very classic home-made dish and also a nourishing soup. The stewed fish soup is tender, smooth, delicious, nutritious, and popular with the public. Although the practice of fish soup is very simple, the soup can be delicious only when the state of water when the fish is in the pan is mastered.
 When stewing fish, it is best to boil it in cold water. If the fish is served after hydrothermal treatment, the protein on the surface of the fish will solidify and denature rapidly, while the internal of the fish has not reached the denaturation temperature. The speed difference between internal and external denaturation is too big, and the freshness of fish stew soup will be reduced a lot, so it is best to use cold water to cook fish stew.
 In addition, if you want to add water in the middle of the stew, you must add boiled water instead of cold water. The temperature of the fish soup boiled in cold water will suddenly drop, and the protein in the fish will suddenly solidify and cannot be fully dissolved in the fish soup, which is not conducive to the delicious fish soup.
