1, choose good quality hairy crabs. When choosing hairy crabs, you must choose fresh and energetic ones, so as to ensure that the hairy crabs are delicious and juicy. 2. Tie hairy crabs. Tie up the hairy crabs, so that we can fully clean them before steaming, and we can also ensure that they will not move during steaming, so as to prevent the hairy crabs from breaking free and causing the crab legs to fall off, which can better maintain its integrity. 3. Steam in cold water. When cooking hairy crabs, don't wait for the water to boil before cooking. High temperature will make crab meat shrink and mature quickly, so that not only the meat will harden, but also the fishy smell can not be completely dispersed, so choose cold water to cook. 4. When steaming, the bottom of hairy crabs is facing up. Because the crab roe is in the belly of the crab, if it is not put upside down, the crab roe of the hairy crab will easily flow out before it solidifies during cooking, causing waste, so it needs to be put upside down. Generally, hairy crabs can be steamed for about 8- 10 minutes according to their body shape. 5. Adjust the sauce according to your own taste. Generally, the sauce eaten by steamed hairy crabs only needs to be blended with ginger and balsamic vinegar, so that the original delicacy of hairy crabs can be better tasted.
