Method 1: Cut the meat and see how it tastes. If it stinks, throw it away. If it doesn't stink, you can add some vinegar or pepper to change the taste, or take the knife off the surface to finish it. Generally speaking, chefs like this practice for a long time.

Method 2: If there is only a moderate smell, and it is a pity to lose it, housewives or elderly people with folk work experience usually wash this meat with boiling water, then get some wine, or put it in a pot and cook it with hot salt for more than ten minutes, which has a very good practical effect on removing meaning.
