Su Xiege Yangcheng Lake Hairy Crab Bian Xiao enthusiastically answers your questions:
In autumn, the climate gradually turns from cold to cold, and crabs grow stronger.
The digestive glands and ovaries of female crabs have grown into crab roe, preparing for the winter and the next year's reproduction (crab roe turns into crab roe in spring). At this time, when you peel off the crab shell, you can see that there are many yellow sticky things in the crab shell and crab tuo, that is, raw crab yellow.
After cooking, the crab roe turns red, and the deeper the red, the thicker the crab roe.
In order to prepare for the winter, male crabs gradually accumulate fat and grow into crab paste (commonly known as crab oil).
Peel off the shell of the male crab, but what you see in the same place is white and sticky, that is, crab paste (crab oil).
After cooking, crab paste becomes translucent. The more crab paste, the stronger the male crab.
Crab yolk and crab paste are not only delicious, but also nutritious, and are the essence of crabs.
In the wild environment, in September of the lunar calendar, the crab roe of the female crab grows the most plump; /kloc-in October, the crab oil of male crabs grows thickest. Therefore, eating crabs used to be called "nine females and ten males". It means: eat female crabs in September and male crabs in October.
Accurately speaking, crab roe is the egg of the female crab, and some female crabs have less crab roe because they are discharged into the water. After ovulation, crab roe is not full. It is better to eat crab paste from male crabs at this time.
