Here's how to clean squid in 10 simple steps! It’s really not that difficult at all. Once you know how it works, you will never forget it anymore. Here we go!
Place the squid on a clean chopping board.
You will probably feel or hear something crunch a little. See that little black thing protruding from the in between the eyes? That’s the beak, the squid’s mouth. Make sure there’s none of that left on the tentacle side. Then throw away the part with the eyes and white gunk (or keep it as bait if you like fishing).
It can be quite large and is transparent. Discard it. Remove any whitish slime that is still inside.
Now peel the skin off. This is quite easy. With your finger nails pinch the skin and see if it tears loose. Then pull the skin towards the back of the body. Also remove the skin on the fins.
The squid meat underneath should be whitish to lightly yellow. Discard the skin. Rinse the cleaned squid inside and outside. Done!
