In fact, under normal circumstances, crab paste is blue-white translucent jelly-like, and it is still in this state after steaming, similar to colloid. However, there are also cases of black cream crabs.
Black paste is not a traditional crab paste.
Every winter and spring is the development and reproduction period of crabs. At this time, the gonads in their bodies are constantly growing, which is also commonly known as crab paste. After cooking, the crab paste of the female crab is red and the crab paste of the male crab is white. After the breeding period, the gonad in the crab shrinks, and at this time, another organ, hepatopancreas, grows and occupies the position of the previous crab paste.
Male crab sauce
Winter and spring are the time for crab reproductive development. After the gonads in crabs grow up slowly, they become crab paste that we often eat. Male crab paste is white and translucent; Mother crab paste is orange, also called crab yellow. After the reproductive period, the gonads atrophy and the hepatopancreas grows, replacing the position of crab paste, which is the appearance of black paste. So the black paste we found on crabs is not the real crab paste, but the hepatopancreas of crabs.
