2. Fill Ejiao with a larger bottle and pour in cold water. It must be cold water. Don't use hot water, or nutrition will be lost. 3. Cover the bottle cap and shake it back and forth repeatedly, so that the donkey-hide gelatin is easier to soften during cooking. It takes about two and a half minutes. )

4. Take out the donkey-hide gelatin, drain the water and put it in a metal plate.

5, put the plate into the pressure cooker, remember, put a small amount of water in the pressure cooker (the amount of water should not exceed the plate), remember to put a little sweet wine in the plate except Ejiao (the amount of sweet wine depends on your own dosage, there is no hard and fast rule).

6, close the lid, open the fire, first simmer with the biggest fire, when the pressure cooker starts to ring, switch to a small fire for about five minutes. :P
