Watercress & Pork Lung Soup

Why people make this soup

Watercress is a seasonal vegetable of autumn and winter, traditionally associated with clearing heat and moistening dryness; simmered with honey dates it is a classic for cooling lung and stomach heat. Many home cooks pair watercress with snakehead fish or with fresh and dried duck gizzard for a rich, savory soup. Nourilo spotted nicely cleaned pork lung at the butcher at a good price, so he pairs it with watercress here, traditionally valued to clear heat, moisten dryness, and clear accumulated lung-and-stomach heat.
