Winter Melon, Clam Meat and Dried Duck Kidney Soup

Why people make this soup

Winter melon (dong gua) is available year-round and is one of the most practical vegetables in the Cantonese kitchen for everyday health maintenance. It is naturally low in calories, gently diuretic, and traditionally associated with clearing heat, reducing swelling, and supporting kidney function — making it a sensible regular choice for anyone watching their blood pressure or blood sugar. The star addition to this soup is clam meat, which is surprisingly iron-rich: 100 grams of clam meat contains around 13.9 mg of iron — more than red meat. Research also suggests that clam proteins may have anti-inflammatory properties and support liver function. Dried preserved duck kidney (chen ya shen) adds a wonderful savoury depth to the broth and also supports digestive health.
