1, hairy crabs should be steamed 10- 15 minutes before eating. Hairy crabs live in shallow waters and are easy to be carried with bacteria. Therefore, hairy crabs must be thoroughly cooked before eating. If steamed for a long time, the meat quality of hairy crabs will become firewood and the taste will be much worse. Therefore, when the time comes, turn off the fire and serve them immediately.

2. However, the time for steaming the hairy crabs is related to the size of the hairy crabs. For example, the crabs with no more than 3 Liang can be steamed for 10 minutes after boiling, and the crabs with 4 Liang can be steamed for 12 minutes after boiling. For crabs with more than 4 Liang, it takes about 15 minutes. Generally, the time needs to be extended by two minutes for each additional one or two.

3. If you are not sure whether the hairy crabs are steamed, you can open the back cover of the hairy crabs. If you see that the crab meat in the cover is solidified, it means that it has been steamed and cooked thoroughly.
