1, the steaming time of hairy crabs can't be generalized, because the time required for a whole hairy crab and a diced hairy crab is completely different.

2. The whole live hairy crab needs to be boiled first, then steamed with high fire for about 5 minutes, and then continued with low fire. The hairy crabs with less than 3 pairs should be steamed for about 10 minute, the hairy crabs with 3-4 pairs should be steamed for about 12 minute, and those with more than 4 pairs should be steamed for about 15 minute. Usually, for every weight gain of 1 2, the steaming time increases by about 2 minutes. In short, the specific time of steaming hairy crabs depends on the size of hairy crabs.
