Steps of making soup with sauerkraut and watercress.
1. Wash watercress, add cold water to the pot and bring to a boil.
I use this kind of cabbage, because it has salty taste, so I should put less salt in the douban soup.
3. Put the cabbage into the pot, add less salt, bring it to a boil, and turn to low heat.
Try this soup, if it is salty, you can cook it. It's light. A healthy home-cooked soup will do.
skill
If there is no packaged pickles, pickles on the market can also be used.
