Pork ribs and fresh watercress simmer into a cooling, nourishing soup. This protein-enhanced, healthy family soup is a Cantonese classic believed to reduce internal heat.
Blanch pork spare ribs in a pot of boiling water for 2 minutes to remove impurities; drain and rinse under cool water.
In a large soup pot, combine pork ribs, ginger slices, carrots, dried honey dates, and 10 cups of water. Bring to a boil over high heat.
Once boiling, reduce heat to a gentle simmer, cover loosely, and skim surface scum as needed. Simmer for 1.5 hours.
Add fresh watercress to the pot, adjusting heat to maintain a gentle simmer, and cook for another 30 minutes. Do not boil vigorously to preserve watercress color and nutrients.
Season with salt and white pepper. Taste the soup and adjust seasoning as needed. Serve hot, ensuring pieces of pork and watercress are in each bowl.
