West Lake Soup

Roland has a cold. What could be better for a cold than a steaming hot bowl of soup? This is my version of a classic thick Chinese soup. I asked my dad if the name of this soup is characteristic of, perhaps, an area in China. He said it was a literal translation of the name of the soup and he had no idea why it is called this!
Anyway, it's really easy and quick to make, and will chase any cold away!
