1.？ The spare crab legs are steamed with garlic for 10- 15 minutes, which can be finished. Steaming can best keep and bring out the sweetness of crab meat, and garlic can make seafood smell strange. I steamed it for 10 minutes, and the meat is just cooked. If it takes too long, it will get old, and it will remain fresh and tender in the right amount of time.
