How to choose crayfish:

1, season: The best time for crayfish is May 5- 10/October, and the yellow meat is plump. Even the three sections on the big claws are elastic teeth and snow muscles from beginning to end;

2, color: look at whether the crayfish is clear water or muddy water, look at the back, red and clean, this is acceptable, and then look at its belly fluff and claws, if it is white and neat, it is basically raised in clear water;

3. size: you should try to buy lobsters that have just grown up. It is too small. After all, it tastes tasteless. Touch its shell with your hand, it's hard and hard, and it's old. As elastic as a nail that has just grown up and changed its shell, you should buy a soft shell.
