Methods for keeping crabs fresh include refrigerator preservation, plastic bucket preservation, and bathtub preservation.
1. Refrigerator storage: tie the legs and pliers of the crab and put it in the cold storage layer of the refrigerator. Cover the crab with a wet towel. Touch the crab's eyes lightly with your hands every other day. If If there is any insensitivity, it needs to be eaten immediately.
2. Storage in plastic bucket: Put the crab into a plastic bucket and add water to about half of its body. It can generally be stored for 3-5 days.
3. Bathtub storage: Put the crab into an idle bathtub and add water to about half of its body. It can generally be stored for 3-5 days.
4. If we buy too many hairy crabs, we can put them in the bathtub and add water to keep them alive, or we can put them directly in the bathtub to keep them alive. Because the sides of the bathtub are smooth, it can ensure that the hairy crabs will not escape. At the same time, putting an appropriate amount of water in the bathtub can also ensure the humidity of the hairy crabs. Add some food for the crabs to keep them for one to two weeks.
How to buy crabs
1. Look at the triangle area of ??the shell: When choosing crabs, we can turn over the belly and look at it. First look at the triangle area of ??the crab shell. They are all white and hard when pinched, indicating that the crab is very fat and the meat is very thick. If the shell in this triangular area is black and soft when pinched, it means that the crab is thin and has little shell meat. Choose a crab with a white, full and hard shell in the triangular area.
2. A crab with a pointed belly button is a male crab: On the other hand, if a crab has a pointed belly button, it is a male crab. Some people like to eat crab meat but not crab meat, so it is okay to choose this kind of male crab. , the male crabs in this season still have a lot of meat. The method is the same, pinch the pointed belly button and choose the hard one. If water comes out and is soft when you pinch it, it means the crab is very thin and the meat inside is not full.
