How long can crabs be cooked?

Generally speaking, it takes about 15~20 minutes to steam crabs.

Steamed crabs 15 minutes is appropriate. If the steaming time is too short, I am afraid that the parasites in the crabs will not be killed and the crabs will not be cooked. If steamed for too long, I'm worried that crabs will get old and taste hard. Under the verification of the majority of foodies, I found that 15 minutes is the best time to steam crabs.
