1, dead crabs generally don't fall off, but live steamed crabs will fall off because they struggle, so they will be wrapped tightly with string and then steamed in a pot, which is not easy to fall off.

2. If it is still easy to drop, you can try: after anesthetizing crabs with wine, put them in a bowl, put the bowl in a pot, drain the water in the pot, and cover the pot, that is, steam crabs, and because crabs are completely drunk, it is equivalent to euthanasia, and they will not struggle or lose their legs.

3. After washing the crab, scald it with warm water first. You need to iron them one by one, and you can't put them down for ironing. If they look yellow, pick them up and steam them so that they won't fall off easily.
