Freshwater fish found in the mountains only eat moss, leaves and crustaceans, so their meat is lean and has a unique flavour.
After being cut the fish is marinated with several ingredients including ginger, garlic and herbs. Then it is folded and placed on a charcoal grill.
The meat is grilled until soft. It costs VND100,000 (US$4.3) per kilogramme. You can find this dish in upland markets in the northwestern region.
