The trick to steaming crabs without losing their legs is to kill the crabs before steaming them.

Specific steps:

Use the knife at the tip of the navel and prick it hard with the tip of the knife. The crab will soon die.

You can also use a knitting needle, a long bamboo stick or chopsticks and insert them into the crab's mouth. After a while, the crab will die.

Put the crab into the steamer at this time, and it will not fall off no matter how you steam it.

Note:

Killed crabs should not be kept for a long time. The crabs should be killed before being put into the pot, and put into the pot as soon as possible.

Before putting the crabs into the steamer, you can open the umbilical cover and put in 2 to 3 peppercorns. This way, the steamed crabs will have a light fishy smell and a strong aroma.
