2. Take out the hairy crabs, soak them in white wine to make them unconscious, and then clean them with a small brush. Soaking hairy crabs in white wine here can not only remove the fishy smell, but also facilitate cleaning. Of course, if there is no liquor, the soaking step can be omitted.
3. Wash the onion and ginger, cut the onion into sections, cut the ginger into half silk, peel and cut into half pieces. After the treatment, prepare a steamer, spread chopped green onion and shredded ginger on the steamer, put the hairy crabs in it, and steam after boiling over high fire 15-20 minutes. Note that if the hairy crabs are soaked in white wine and are in a coma, they can be placed directly without binding, otherwise we need to bind the hairy crabs.
4. When steaming hairy crabs, chop garlic and ginger, put them together in a bowl, add rice vinegar and salt into the bowl and stir well to make a sauce. After the hairy crabs are out of the pot, they can be dipped in the sauce.
