西洋菜汤 - Watercress soup

It's been rainy all weekend. Soup is just the right thing to have. I have seen many variation of this soup. Here's my version:

Ingredients:

1 bunch of watercress, trimmed
2 medium carrots, chopped into chunks
chicken bones
3 honey dates 密枣
Handful of goji berries 枸杞
small handful of north and south apricot kernels 南北杏
Approx 2.4 lt water
salt to taste


Method:
1. First, put everything except Watercress and salt with the bones to bring water to boil. Remember to drain away the scum for clearer soup.
2. Then in the last 15 minutes, I put in the watercress. Season with salt to taste.
