1, first "raise" the crab in the water for a while to make it spit out dirty things and empty the intestinal contents; Then use a toothbrush to brush the crab claws and legs, which are often hairy and easy to hide evil people.

2. Press the blue crab, poke the chopsticks (two in parallel) into the joint of the tail cover, and stick them to the top of the cover slowly (note that if you poke them straight, they will destroy the white of the crab paste, which will be lost when washing). Then, press the flippers of the blue crab and push the chopsticks up like a lever principle, and the cover of the saw-edged blue crab will be opened.

Pull out the stomach pouch and gills, rinse the cover, and finally, wash the residue of the excretory cavity in turn, cut off the rubber band or red rope on the crab claw (if the crab claw is dirty, you can also brush it), and then rinse it in the water to cook.

Extended data

The blue crab burrows in the shallow sea near the shore and in the sediment bottom of the estuary. It is carnivorous and sometimes eats corrupt small animals. Once dead, there may be toxins in the gastrointestinal tract of the blue crab and spread to the muscles, so the dead blue crab is not suitable for eating. After buying, it is best to put the blue crab in clean light salt water for temporary cultivation and purification, which is helpful to clean the digestive organs of the crab.

Bacteria and parasites, such as Vibrio parahaemolyticus and Paragonimus, are easily enriched on the body surface and body of crabs. It is not recommended to eat them raw, and they must be steamed and cooked thoroughly. It should be reminded that the cooking method of "drunken crab" can not effectively kill parasites and pathogens that may exist in crabs.
