1. Rinse the slaughtered sturgeon in water first, and then use boiling water of about 80 degrees, that is, when the water begins to bubble, scoop out the water and scald the sturgeon skin with water.

2, sprinkle some salt and white vinegar on the sturgeon, don't be too much, enough is enough.

3. Next, slowly scrape with a knife or bamboo stick, clean copper wire balls for pot washing, etc. Be patient when scraping, and never scratch the fish skin.
