Soak the bean skin soft in advance and blanch it with Flammulina velutipes. After cold water, screw out the water for later use.
Put the sugar directly into the bean skin, and put the remaining seasoning into the bowl.
Put peanut oil in the pot until it smokes. Turn off the fire and pour it into the bowl.
Stir well, add bean skin and Flammulina velutipes and serve.
