We can wash the fish first, put the fish in cold water, then drop a little edible white vinegar in the water, or add a little white pepper, and cook it after about ten minutes, and the earthy smell will magically disappear.

Hold it with your hand and gently pull it in the direction of the fish head, which can be easily removed, so that there is no fishy smell when cooking.

5. When frying fish, take a proper amount of rice wine, soak the fish in rice wine for one minute, then wrap it in flour and fry it in an oil pan to remove the peculiar smell of the fish.
