It is therefore possible to find this crustacean in many parts of the world, even if its origins seemingly are Chinese. Used in the recipes of first courses, where the smallest species are utilized, or in those of appetizers and second courses, the crab is a tasty crustacean formed by two large frontal claws, eight small lateral legs and a hard carapace.

A different matter, of course, is that of crab meat, which is sold already packaged and can be consumed within about 12 months. In fact, it is possible to find crab meat frozen or preserved in water and salt in tin or glass jars.

How to clean the crab

Cleaning a freshly caught or purchased crab is not a complicated operation.

What you will need to clean it is: a pot, a chopping board, a well-sharpened knife, a nutcracker, a wooden skewer and a teaspoon.

Step 1. First you will need to blanch the crab for a few minutes. Then dip it in a large pot and cook it in boiling water for about 10 minutes.

Step 2. After having lifted it and let it cool down completely, place it on the chopping board and remove the claws, side legs and tail, directly with your hands.

Step 3. With the tip of the knife, penetrate the shell of the crustacean and exert slight pressure to open it in two.

Step 4. Then remove the gills, stomach bag and lungs.

Step 5. At this point, with the help of a teaspoon, remove the white pulp. It is possible to recover also the brown one, with a softer consistency, and the red one, the coral. All three pulps can be used for different preparations, depending on your taste.

Phase 6. With the nutcracker it will be necessary to open the claws, removed at the beginning, to recover with the skewer the greater part of white pulp that the crab contains.

Tip: To avoid suffering the crab, before boiling it, transfer it to the freezer. Freezing will cause the crab to fall asleep slowly and avoid the torment of the boiling pan.
