1, fresh can be omitted. If frozen octopus needs to be thawed naturally, don't heat the water, it tastes strange and not delicious.

2. Unfold after thawing, find the hole at the bottom, squeeze by hand, and squeeze out the teeth. Can't eat.

3. Take a pair of scissors and cut it from the bottom up to the back of your head. Take out all the internal organs, throw them away, rinse them, and find out all the eyes. They are full of ink and can't be eaten.

4. Rinse it again. The last step is to tear off the skin of the small octopus by hand, otherwise it will affect the taste. Chop the fried green pepper and blanch it with mustard. Don't eat it raw.
