Clean the blood on the surface, then pour out the water, prepare some salt, sprinkle it on the eel, and then start scratching, so that the mucus on the eel surface can be completely removed. When the foam is rich, it can be thoroughly cleaned with clear water.

It's best to wash it several times. Of course, you can also catch eels and wash them with running water. After the water becomes clear, drain the excess water in the basin, sprinkle with white pepper and cooking wine for pickling, and then remove the fishy smell for later use.
