1, hairy crabs can be cooked and eaten. Put the hairy crabs in a large washbasin filled with clean water, add a little salt into it, quickly cover it with a lid, press it, and take it out one by one after 5 minutes.

2. Wash the appearance with clear water and put it into the container. The former process is to stimulate hairy crabs to spit out the dirt in their stomachs with salt water.

3. Put an appropriate amount of cold water into the pot (subject to the fact that it can submerge the hairy crabs in the pot), put the hairy crabs belly up into the pot, quickly cover the transparent pot cover, press the pot cover, and cook with strong fire until the crabs die slowly. After the water boils, cook for 15 minutes until the crab shells are bright red. When the crab meat is ripe, turn off the fire and suffocate for 3 minutes, and then take out. Boiled hairy crabs are finished.
