Thanh Hóa, Vietnam

Vietnam

Thanh Hóa is a province on the narrow coastal plain of north-central Vietnam, roughly 150 kilometres south of Hanoi. The province occupies a transitional zone between the Red River Delta culture of the north and the central Vietnamese traditions further south. The provincial capital, Thanh Hóa city, sits at the mouth of the Mã River where it opens toward the Gulf of Tonkin. The province has one of the largest populations of any Vietnamese province, and its cooking is distinguished by an emphasis on cured and fermented preparations suited to the hot, humid climate. Nem chua from Thanh Hóa is the food product most associated with the province outside its borders. The local version is tighter and sourer than southern variants, with a higher ratio of lean pork to skin, and the proportions of garlic and fish sauce have been refined across generations of producers. Shops along the main streets of Thanh Hóa city stack parcels of nem chua for sale, and travellers on the Reunification Express train passing through the province buy parcels from platform vendors. The province also produces bánh cuốn Thanh Hóa, a steamed rice roll, and nem nướng grilled sausage, but nem chua remains the product that travels furthest.

Sausages from Thanh Hóa, Vietnam

Nem Chua

Thanh Hóa, Vietnam

Nem chua is a Vietnamese fermented pork sausage eaten raw, straight from its banana leaf wrapping. Made from lean pork pounded to a smooth paste, it incorporates strips of boiled pork skin (bì), garlic, fish sauce, sugar, and salt, then wrapped tightly in banana leaves and left to ferment at room temperature for three to five days. Lactic acid bacteria do the preserving work, acidifying the paste and firming the texture without any heat. The finished sausage is pink, fragrant with garlic, and sour from the ferment. Vendors sell it in small parcels tied with a strip of the same leaf. Buyers unwrap it at the table, often eating it with a toothpick alongside fresh chilli slices and pickled garlic. The most cited origin is Thanh Hóa province in north-central Vietnam, where the technique and proportions have a long history. Versions from Lai Vung in Đồng Tháp and Bình Định province each have local champions, but Thanh Hóa remains the benchmark.
