1. Cover with a wet towel and place in the refrigerator.

2. If we want to preserve fresh swimming crabs, remember not to untie the ropes that tie them, let alone clean them. Just place the crabs directly into the freezer and cover their backs with a damp towel. When we need to cook, take out the crab, test the eyes to confirm that it is still alive, and then cook it directly.

3. The reason why this method can preserve freshness is because at the temperature of the refrigerator, crabs will enter a state similar to dormancy. In this state, they can generally last for four to five days without dying. . When we need to cut open fresh swimming crabs for frying, if we are worried that the swimming crabs are too vigorous and difficult to handle, we can also put the live crabs in the refrigerator and let them blow air for a while, so that the crabs will enter a state of near dormancy and laziness. Looks, easier to handle.
