1, hairy crabs are not fully mature, eat too early, crab roe is too tender, and it will taste bitter.
2, the problem of practice, because hairy crabs grow up in water, so there may be some dirty things in them that are not cleaned and will be bitter to eat.
Crabs must be kept in clean water for two days before they are bought and put into the pot. After two days, the crabs were basically "clean". A clean crab has all the dirty things in its stomach, so the crab roe naturally won't suffer.
matters need attention
1, tender crab crab yellow and bitter can be eaten.
Bitter crab roe is characterized by color, thinness, no caking, and a small amount of crab roe, which is mainly caused by the fact that the crab is too tender and not fully developed. This crab roe is edible, but the bitter taste is not good.
2, dirty crabs can not eat crab yellow bitter.
Crab yolk is full, but its color is slightly lighter than that of normal crab yolk. Because the crab yolk is composed of egg cells, crab digestive tissues and gonad tissues, it is also possible that the crab has no bitterness caused by "nourishing", and there are dirty things left in the crab yolk. This crab yolk is not suitable for eating.
