(2) Frontal scales: scales at the junction of the chin and abdomen of fish. This part of the fish scale is firmly attached to the fish because it wants to protect the heart of the fish. Scales are small and difficult to find, but they are the main source of fishy smell after cooking. Especially when adding marine fish, the forehead scales must be removed.

(3) Black in the abdomen: There is a layer of black in the abdominal cavity of fish such as scaly fish and carp, which not only brings fishy smell, but also affects the appearance. Be sure to scrape it clean when washing.

(6) Tendons in meat: There are slender white tendons on both sides of the body of carp and other fish, which should be removed during processing. After snail killing and scale removal, the fish body is ground flat from beginning to end, and a dark line can be seen on the side of the fish body, and the white rib is located below this line. Cut a knife near the gill cover in front of the fish and you can see the white tendon.

Frozen fish just taken out of the refrigerator must not be scalded with hot water if you want to cook it immediately. In hot water, only the skin of frozen fish is heated, and the speed of heat transfer to its interior is very slow. In this way, not only the frozen fish is not easy to melt, but also the skin of the fish is easy to be scalded, which leads to degeneration of protein and affects its umami and nutritional value.
