In the meantime, wash and prepare the Chinese cabbage and cut into thin strips. Pour into the saucepan, stir well and cook covered for approx. 5 minutes.
Pour in the broth, bring to the boil and simmer covered for approx. 5 minutes. Finely puree the soup with the hand blender or in a blender and season with pepper, ginger, nutmeg and, if necessary, salt.
Simmer uncovered for a few more minutes. Serve the soup and add cream to taste.
