Potato, Tangerine Peel and Crucian Carp Soup

Why people make this soup

Crucian carp is a humble everyday fish — deeply nourishing in a quiet, unpretentious way. Its flesh is delicate and fine-grained, with a naturally sweet flavor and very little fat. In traditional Chinese food therapy it is one of the go-to ingredients for anyone whose digestive system runs cold — that is, people who tend toward bloating, poor appetite, loose stools, or low energy after meals. The traditional approach with this fish is to pan-fry it first until golden on both sides, then add boiling water and simmer — this technique turns the soup milky white and creamy, drawing out the protein and mineral goodness of the fish.

Potato, often overlooked as a health food, is actually a wonderful companion in this soup: rich in potassium and B vitamins, it is associated in research with supporting mood stability and resilience against low spirits — a welcome bonus in uncertain times. Tangerine peel and ginger add warmth, aid digestion, and reduce any fishy notes from the carp.

Method

1. Peel and cut the potatoes into chunks. Soak and rinse the tangerine peel. Pit the red dates.
2. Clean and scale the crucian carp thoroughly. Pat dry.
3. Heat a little oil in a pot or deep pan over medium-high heat. Pan-fry the fish on both sides until golden and slightly crispy.
4. Add a splash of Shaoxing wine, then immediately add 2.1–2.4 L of boiling water. Bring to a rolling boil — this is what makes the soup turn milky white.
5. Add the potato chunks, ginger slices, tangerine peel, and red dates.
6. Reduce to medium heat and cook for about 40 minutes until the soup is creamy and the potatoes are tender, reducing to approximately 1.2 L.
7. Serve warm.

Nourilo’s Tips

When it comes to crucian carp, the white variety (bai ji) is worth seeking out — the flesh is sweeter, finer, and has far less of the muddy taste common in the African or black carp. Available at Chinese or Asian grocers, or online. This soup is safe and nourishing for the whole household. It is particularly well suited for those with gastric ulcers or a cold stomach constitution, as well as for pregnant and breastfeeding mothers who need gentle, easily digested nutrition. For best flavor, always add boiling (not cold) water after frying the fish.
