1, cooked crabs can be frozen in the refrigerator, but it is best not to freeze for more than three days. Frozen crabs have no nutritional value, and heated crabs taste worse. Therefore, it is best to put the cooked crabs in the fresh-keeping room and eat them immediately after meals, because any food can't be preserved for too long, which will affect the nutritional value of the ingredients.

2. After the hairy crabs are cooked, it is best to eat them on the same day. Don't save them. Because crab roe is easy to deteriorate after being cooked, how long the water-containing molecules in crab meat will be left behind will lead to water loss, thus losing the delicacy of hairy crabs themselves. If it is a spicy hairy crab, a layer of oil can protect the water from losing. Moreover, the cooked hairy crabs will be preserved again, resulting in a decline in taste.
