Wash the squid and put it in the refrigerator for freezing. When cleaning squid, it is necessary to clean its black mucosa, which is the main source of fishy smell. The mucus on the squid should also be cleaned, and some edible salt should be added appropriately to completely clean it. In addition, the internal organs of squid should be cleaned. It is very convenient to put the washed squid in a fresh-keeping bag and freeze it in the refrigerator. It can be thawed directly when you eat it next time.
