1. Go to the seafood market to pick fresh live crabs in the morning. Crabs should be the first choice, with strong vitality, fast crawling, much spitting and loud voice. Touch the crab legs with your hands, and the crab that can turn over quickly and easily is the fresh crab. Although dead crabs are much cheaper, steamed crabs also have a fermented taste and a bad taste. And bacteria reproduce very fast. I don't know how long I've been dead. I may have diarrhea after eating it.

2. Cut off the white silk on the crab and the rubber band that binds the crab, so that there will be no rubber band smell when steaming, and then scrub the crab shell with a toothbrush under running water.

3. Steamed crabs on the pot. Add a proper amount of cold water to the steamer, not too much, and keep a distance of 3~5cm from the steamer. Put the crab belly up and back shell down into the steamer, and put a piece of ginger on it to remove the fishy smell, so that the crab is heated evenly and the crab yellow does not flow out.

4. According to the size of crabs, the steam in the steamer starts to be timed, and the small one can be steamed for 12 minutes, and the big one can be steamed for 15 minutes. Crabs must be steamed before eating, but not for too long. After a long time, crab meat will become old and firewood. Finally, prepare a ginger vinegar juice, cut appropriate amount of ginger and minced garlic, add vinegar to make ginger vinegar juice, and eat crab meat with ginger vinegar juice. Delicious and nutritious!
