1. Wash freshwater fish, put them in cold water, and then pour a small amount of vinegar and pepper into the water. After this treatment, freshwater fish will have no earthy smell.

2. Mix 25 grams of refined salt with 2500 ml of water, soak the live fish in salt water, and the earthy smell will disappear after one hour. If it is a dead fish, you need to soak it in salt water for two hours, or you can get rid of the earthy smell.

There are two white ribs on both sides of the carp's back, which is something that makes a special fishy smell. Pay attention to remove these two white tendons when slaughtering, so that they will not smell after cooking.

When killing freshwater fish, try to wash the blood of river fish clean. Add onions, ginger, garlic and other seasonings when cooking, and the earthy smell can be basically removed.
