1, brush with a toothbrush

Prepare an old clean toothbrush and gently scrub the crab's back and abdomen. At the same time, when cleaning, you can take off the rope or straw that binds the crab, move it, brush it and put it back in place.

Step 2 soak in salt water

You can prepare some salt water and soak crabs in salt water. Salt water has the function of sterilization and disinfection. Some dirt on the surface of crabs will be soaked after soaking, and then washed repeatedly with clear water, especially where ropes or straws are tied, which can still be washed clean.

Step 3 use baking soda

You can prepare some baking soda powder, then sprinkle it on the surface of the crab, let it stand for about half an hour, and then rinse it with clear water. You can brush it with a small brush, which will wash the crabs very clean.

Selection method of crab

1, see vitality

In the process of selecting crabs, you can turn them over and put them on the ground, so that their stomachs are facing up. If the crab can turn over quickly, it means that the crab is quick, full of vitality and fresh and plump. If crabs can't turn around quickly, have poor vitality and are not fresh, it's best not to buy them.

Step 2 look at the navel

Observing the navel is the most direct way to choose crabs, because the belly is the place with the most meat on crabs, so you can press the navel with your fingers. If the navel is round and elastic, it means that the crab is fat. In addition, the triangular navel is a male crab, and the round or oval navel is a female crab.

Step 3 pinch the crab's feet

When picking crabs, you can gently pinch their feet. If you feel resistance in the process of kneading, the sunken part will recover quickly after kneading, indicating that the crab is fat and beautiful. If the kneading process is relatively easy and the sunken part cannot be recovered, it means that the crab is relatively thin.
