2, the washed crab can be soaked in white wine for a while, and the crab can be drunk to avoid hurting people. You can also grab both sides of the crab's back shell, and the crab can't catch people.
3. Brush the crab's back shell with a toothbrush, and open the shell several times in the triangle area of the abdomen, where there is a lot of sediment. A few feet and two pliers of the crab also contain a lot of fine sediment and stubborn dirt, so it is necessary to brush them hard. It takes about 2-3 times to brush the outside of the crab with clean water.
4. Remove the internal organs of the crab from the back shell. Open the back shell forcibly, and you can see the heart and other internal organs. If there is crab roe on the back shell, all the internal organs should be dug to keep the crab roe. Without crab roe, you can throw it away directly. There is no meat on the back shell of the crab.
5. Next, remove the crab mouth and crab gills, then rinse them with water, and the inside and outside of the crab will be cleaned.
