It takes about 15 to 20 minutes to steam crabs in a rice cooker. Generally, if the color of the hairy crabs changes color, it means that the hairy crabs are cooked. But if you encounter particularly large crabs, you need to increase the time as appropriate.

Notes on steaming crabs in a rice cooker:

1. When steaming crabs, be sure to use cold water in the pot, so that the crab legs will not fall off easily and the steamed crabs will be more attractive. . Be sure to remember to cover the pot, so that the crab roe in the steamed crab will be softer, waxier and more textured, and will not become yellowish.

2. Steam for 15-20 minutes after the water boils. At this time, the meat is fresh and tender and more nutritious. If the steaming time is short, it will not be cooked. If the time is long, the crab meat will become old and taste bad.
