Soups
Chayote, Corn and Dried Whelk Soup
traditionally associated with clearing mild internal heat, nourishing yin, and moistening the lungs
Why people make this soup
After a string of restaurant meals or a few days of rich food, you might feel a vague sense of “heat” — a mild dry throat, slight thirst, or just that heavy feeling of having eaten too much. Bitter herbal teas would work, but they leave an unpleasant aftertaste. Bro Niu’s preferred solution in this situation: a pot of this gentle, naturally sweet chayote and dried whelk soup. It clears mild internal heat and nourishes yin without being harsh or too cooling — making it suitable even for those with slightly cold constitutions.
The soup also makes a great everyday option for people managing blood pressure, blood sugar, or weight, as all three main ingredients are supportive in these areas.
Who it suits / who should be cautious
- Suitable for most adults and the whole family; can be drunk daily
- Particularly useful after periods of rich eating, or when feeling slightly “heaty” or dry
- Excellent for those with high blood pressure, diabetes, or those watching their weight
- Suitable during pregnancy (Bro Niu confirmed this); adding snow ear fungus (xue er) is fine if there is nasal dryness or nosebleed
- During a cold or flu, replace the dried whelk with dried scallops (yao zhu), as whelk is not recommended during illness
- If dried whelk is unavailable, fresh mussels (dan cai), oyster meat (hao chi), or dried mushrooms can be used as substitutes
Why these ingredients (the food-therapy logic)
- Chayote (he zhang gua): A mild, moisture-rich squash; in food therapy associated with clearing stomach heat, supporting digestion, and soothing the lungs; also beneficial for blood pressure and blood sugar regulation
- Corn (su mi): Naturally sweet and diuretic; in food therapy associated with clearing heat and supporting kidney function; corn silk (if available) has even stronger heat-clearing properties
- Dried whelk (xiang luo gan): A high-value seafood ingredient in Cantonese cooking; traditionally associated with clearing heat, moistening the lungs, nourishing blood and qi, and supporting yin — suitable for yin-deficient constitutions; not recommended during active colds
- Pork soup bones: Provide richness and depth of flavour; protein and collagen
Ingredients (4 bowls)
| Ingredient | Amount | Notes |
|---|---|---|
| Chayote | 2 whole | Peeled and cut into chunks |
| Corn | 2 cobs | Husked and cut into sections |
| Pork soup bones | ~450 g | Blanched to remove impurities |
| Dried whelk | 2 liang (~75 g) | Soaked for 30 minutes before use |
| Fresh ginger | 2 slices | |
| Water | 6–7 bowls |
Method
- Blanch the pork soup bones in boiling water to remove impurities. Drain and rinse.
- Soak the dried whelk in clean water for about 30 minutes until softened. Drain.
- Peel the chayote and cut into large chunks. Husk the corn and cut each cob into 3–4 sections.
- Place all ingredients — bones, whelk, chayote, corn, and ginger — in a pot with 6–7 bowls of water.
- Bring to a boil, then reduce to a low simmer. Cook for about 1.5 hours until approximately 4 bowls remain.
- Season lightly with salt. Serve and drink.
Bro Niu’s tips
Dried whelk is not recommended during a cold — substitute with dried scallops (yao zhu) instead. If you cannot find dried whelk, fresh mussels (dan cai) or oyster meat (hao chi) are good alternatives with similar yin-nourishing properties. Snow ear fungus (xue er) or carrot can be added freely to enhance the nutritional value.

Q (Can): If I don’t have whelk or dried scallops, what else can I add? Bro Niu: Fresh mussels (dan cai) or oyster meat (hao chi) work well — both nourish yin and support kidney function.

Q (Toby): Between west African and American dried whelk, which is better? Bro Niu: I find the American dried whelk has a better, fresher flavour.
