The time for steaming crabs varies depending on the type and size of the crabs, as follows:
1. About 200 grams of hairy crabs: steaming for 15-20 minutes is best. If the crab is large, it can be extended to 20-25 minutes appropriately.
2. Flower crabs: Flower crabs are relatively fresh and tender, with a smaller body size than hairy crabs. They are usually steamed for 10-12 minutes.
3. Chinese mitten crab: Chinese mitten crab has tender meat and thin shell, and is best steamed for 12-15 minutes.
If it is a crab weighing less than 3 liang, the steaming time is 10-15 minutes; 3 or more crabs, steaming time is 18-20 minutes; Larger crabs can be appropriately increased to 22-25 minutes. During the steaming process, it is recommended to use cold water in a pot and mix it with seasonings such as ginger shreds, scallions, cooking wine, etc. to remove the fishy smell.
