The reasons why crab yellow is thin and soft are as follows:
1. The mature time of crab hard yellow is not reached
Soft yellow itself is watery, which may be more soft yellow and less hard yellow. Crab yellow is the ovary and digestive gland in the female crab, which is orange and delicious. The female crab will see hard yellow when it is steamed in mid-October. Before this, steamed soft yellow and soft yellow+hard yellow (a small amount).
2. Male crabs are selected.
At any time, the yellow of male crabs is less than that of female crabs at that time, which is sparse and will not harden when steamed. But in the middle and late October, the male crab matured, and his stomach was full of paste and translucent paste. Before that, the male crab had almost no paste. Crab paste is a collection of semen and organs of male crab seminal vesicle, which is translucent, sticky and a little greasy.
3. It takes too long to steam the crabs
After the hairy crabs are boiled, put them into the general steam for 8 minutes. If the crabs of 4 pairs are steamed for 1 minutes. Steam for 2 minutes is too much, and the meat inside has shrunk very little. In addition, steam enters the crab and becomes watery after steaming.

Methods of selecting crabs:
1. First of all, we should distinguish male crabs from female crabs, whose navel is round and whose navel is irregular triangle. The siege line is male crabs, and only female crabs are yellow.
2. The color of crab abdomen is slightly yellow, which means it is better. If there are large transparent or translucent abdomen, it means it is not fresh and tastes bad.
3. Look at the oblique angles on both sides of the crab shell. There are many colors, which means it is fat. If it looks empty, it means it is thin and has no meat.
4. Look at the joint between the calf and the crab cover. The greater the separation, the fatter it means. You can also turn the crab back down. If you can turn it over at once, it means it is very fresh.
