Crab paste is a bluish-white, translucent jelly-like liquid in natural state, and it is a viscous and translucent colloid after steaming. There are two kinds of crab paste: crab paste and crab paste. Crab paste tastes a little sweet, and crab paste tastes a little fishy. Crab paste is the accessory gonad of male crab. Most of the crab paste we usually eat comes from the gonads and some internal organs of crabs. When the male crab matures, the accessory gonads are more developed, occupying most of the reproductive system, and may even push the crab shell upward, so the mature male crab paste is fatter.
Crab is a crustacean of Lepidoptera. Its body is protected by a hard shell and breathes through its gills. Taxonomically, it belongs to the same class of animals as lobster, shrimp and hermit crab. Most kinds of crabs live in offshore areas or in the sea, but some kinds of crabs live on land or in fresh water.
