In the Jiangsu, Zhejiang and Shanghai generations, hairy crabs have been regarded as delicacies on the dining table since ancient times. For example, in the Dream of Red Mansions, Jia Yucun used hairy crabs at Zhenfu and Daguanyuan Crab Banquet, while folk wine-brewed hairy crabs and hibiscus hairy crabs were handed down from ancient times. It can be seen that people in Jiangsu, Zhejiang and Shanghai have deeply studied and loved how to eat hairy crabs.

Secondly, the taste problem.

Portunus belong to sea crabs, which are suitable for eating meat. Because sea crabs can generally grow bigger and have thick meat, which makes them chewy. However, hairy crabs, especially those in Yangcheng Lake, are suitable for eating. Although the crab shell is thin and brittle, it is not big, but no matter what food it is mixed with or steamed separately, its umami will make other foods taste different. People in China pay more attention to eating and the role of seasonings. Compared with sea crabs, hairy crabs are more delicious. It's like crayfish itself has a little meat, but people still like to eat it. In fact, that's the taste they like.

Third, things are rare.

Portunus is not rare. Our country has a long coastline, and there are many farmed in coastal areas. However, hairy crabs, especially Yangcheng Lake, are rare because of their special origin. In addition, there are requirements for the season of eating, so it will attract attention as soon as it is listed in autumn. Needless to say, the local crabs in Yangcheng Lake, such as Crab Palace and Su Crab Pavilion, are also popular.
