Fish is the most delicious meat food. The flesh of fish has no coarse ribs and the microstructure is not compact. This is the intrinsic reason why fish breaks easily when cooking fish. Since most foods conduct heat poorly during heating, and since the whole fish is usually cooked, if the food's temperature control ability and heat conductivity are not coordinated, the result will be broken fish.
As long as you remember the succinct formula of hot pan, cool oil, hot pan, hot oil. This is also is basic common sense for a chef. You have to understand the meaning of these two words, in order to make fried fish not sticky, cooked fish not broken, cooked fish not broken is entirely determined when frying, the fish does not stick will not be broken, therefore, the key to the frying process.
Hot pot and cool oil means that the pot needs to be heated and then add cool oil, wait for the oil to be hot at the same time and then pour out the oil, so that the deep frying will not stick to the pot. It is important to note that the oil in the pot is heated, pour out and add a little cold oil. This is the hot pot cooling oil, the oil in the pot needs to be heated up to 80%. Hot pan hot oil means that the pan itself is hot and the oil is hot. This method is usually used by restaurant chefs. Because restaurants often use large pots of oil and cook all the time, the oil is recycled, it is always hot oil, so the chef cooks quickly and can do a good job.
Another tip to prevent fish from breaking up if you're at home is to fry the fish before cooking. If you are frying the fish, wrap it in a thin layer of water starch and put it in a pan to fry. Pay attention to the temperature of the oil. When cooking fish, don't use too much heat or too much soup. Soup just over the fish is fine. Once the soup is cooked, it should be simmered over low heat until it thickens and becomes fragrant. While simmering, turn the fish as little as possible. To prevent the fish from sticking to the pot, you can lift the pot and shake it gently, but this is not recommended if you have little wrist strength, especially for girls.
