What kind of dark plum is used to make sour plum soup? Is it good to use bagged dark plum?
You can buy it in the supermarket. If you don't have ebony, you can replace it with a bag of ebony. Practice: put the ebony in a clean steel pot, and don't put it. First, bring the soup to a boil with a large fire, and then lower the fire to more than 1 hour until the soup has a taste. Take it out and put it in the refrigerator for 30 minutes. Take it out and eat it. It tastes best.
