Methods to prevent fish from rotting when cooking fish:

1. Before cooking fish, fry the fish in the pot. When grilling fish pieces, they should be coated with a thin layer of flour and egg yolk liquid. The oil temperature should be high rather than low when frying, until the fish body turns yellow.

2. When cooking fish, the heat should not be too high and water should not be added too much. It is better to slightly submerge the fish in the pot. After the soup boils, simmer over low heat until the soup is thick and fragrant.

3. During the firing process, try not to turn it. If it sticks to the pot, lift the pot and shake it gently.

4. When cutting fish into pieces, the knife should be cut in the direction of the fish bones. For example, when cooking yellow croaker, insert two chopsticks into the belly of the fish from the mouth, clamp the intestines and stir them a few times, then pull out the intestines. Do not perform a laparotomy to remove the internal organs.

5. When serving the plate, do not use chopsticks to pick it up.
