What should I do with the pig tongue I bought?

1, when processing the bought pig tongue, put it in a pot, add clear water, boil it with strong fire, take it out, put it in clear water for cooling, and then scrape off the white material on the surface with a scraper.

2. After scraping, cut off the upper part of the pig's tongue, clean up the mucus inside, and finally store it in the refrigerator.
