Fresh Smilax Root, Mung Bean, Hyacinth Bean & Job's Tears Pork Rib Soup

Why people make this soup

Hot, humid weather brings out the worst in skin conditions. Whether it is heat rash appearing in skin folds, or eczema flaring up in the sticky summer air, many people in Cantonese households have grown up with this soup as a seasonal companion. Fresh smilax root (tu fu ling) is the hero ingredient — a rough brown rhizome available at Chinese or Asian grocers and herbal supply shops, who will often peel and slice it upon request. Modern research confirms what Cantonese kitchen wisdom has long claimed: it has measurable anti-inflammatory, antibacterial, and antifungal properties. Paired with mung beans (cooling, blood-clearing), flat beans (spleen-supporting), and Job’s tears (dampness-draining), the result is a soup that gently but consistently addresses the “damp heat” internal environment that Chinese medicine associates with skin flare-ups. The pork ribs provide flavour and a gentle savoury background; the honey dates add a touch of sweetness.

Method

1. Soak and rinse the mung beans, flat beans, and Job’s tears.
2. Peel and thinly slice the fresh smilax root (Chinese or Asian grocers and herbal supply shops will often do this upon request). Note: the flesh will turn rust-coloured quickly after slicing — this is normal.
3. Blanch the pork ribs in boiling water briefly to remove impurities; drain.
4. Place all ingredients in a pot with 2.4–2.7 L of water.
5. Bring to the boil, then simmer for 2 hours until the liquid reduces to about 1.2 L.
6. Serve the soup and solids together.

Nourilo’s Tips

Fresh smilax root gives better results than the dried version and is worth seeking out at Chinese or Asian grocers and herbal supply shops. Don’t be alarmed if the cut surface turns rust-brown after slicing — it is a natural oxidation reaction from the mineral content and does not affect the medicinal properties. This soup has very little herbal flavour and is easy to drink for both adults and children. For people with a cold constitution, swap mung beans for adzuki beans and add dried tangerine peel.
