The first choice is to look at the appearance of hairy crabs. The hair between the claws of a good hairy crab is yellow, and the crab shell is blue-gray and shiny. The navel of a crab is convex and round. The limbs are complete, naturally bent and powerful. Good crabs are full of energy. Moreover, when choosing hairy crabs, you must choose live ones. We can put a cushion by hand. After death, the crab will turn into a pool of water, and the weight of the crab can be checked by hand. Heavy hands make the meat hard, while light hands make the meat loose.
Fresh crabs smell like ponds or mud ponds, but they are not dirty. If you smell fish, the crab may have gone bad. To judge whether a crab is alive or not, it is better to pull up its claws. The legs of fresh hairy crabs contract badly. The legs of dead or dying crabs are fragile and easily broken.
I have to buy it anyway, so that I can uncover the navel of the crab. You can see crab roe when your navel is exposed. If the crab roe is neat and complete, it is a good crab. Lime reminds everyone that you must choose live hairy crabs, because the oxyacid in dead hairy crabs will decompose to produce histamine, which is toxic. And the longer we wait, the more this toxic substance will be. Eating it will cause diarrhea!
