Why is the sour plum soup in the hotel better than your own?

1. The prepared sour plum soup can't be eaten all at once, so you can put it in the refrigerator for a few days. But at room temperature, sour plum soup is very easy to deteriorate. If you see thin bubbles floating on the surface, it means that it has deteriorated and you can't drink it.

2. Sour plum soup with licorice will have an astringent taste. Putting some ice cubes when drinking can reduce the astringency.

3, the sour plum soup made by novices is likely to be too strong or too weak, and the ratio of heat to water can only be tried!
