After the first step is completed, it can only be said that 80% of the earthy smell has been removed. If you can accept it, then you can skip the second step! However, it is recommended to take a closer look, because this step is more important.
The second step; "blanch, remove the surface layer" After the previous mucus was removed, there was a layer of mucous membrane left, which also smelled earthy, and there were many bacteria and parasite eggs, which was not good for the body. Therefore, this layer must be removed. Boil a pot of water. After the water is boiled, put the loach into the pot and blanch it 1 min. After taking it out, you can see that there is a yellow-white film on the surface of loach. At this time, rinse with cold water and tear it off.
