First of all, we should clean the surface of the squid and just buy it back, because we don't know what water it has been stocked in before. It is recommended to put the squid in the water for about an hour, dead or alive, so that it can have a process of changing water.
Then cut the belly and tail (squid whiskers) of the squid from the connected part. Cut under the abdomen with a knife, and take out the internal organs of squid. Be especially careful that squid has guts. Everyone who has cut fish knows that guts are bitter and must not be broken. Once broken, the taste of the whole fish has changed. Then after taking out the squid viscera, wash the inside.
Squid eyes, depending on your personal preference, can be taken out to eat or dried. The nutritional value of fish eyes is still good. The thin film on both sides of squid abdomen can or can not be used.
Then separate the squid one by one, you can cut them with scissors, or you can cut them with a knife to see your personal hobbies, and then clean them one by one for later use.
