What is Nam ngiao?
Nam ngiao is a noodle soup known for its bold, spicy and sour taste. It combines soft rice noodles—often khanom chin, which are fermented rice vermicelli—with pieces of pork or beef, chopped tomatoes, and cubes of curdled blood. The broth is flavored with thua nao, a fermented soybean paste, and often includes dried Bombax flower cores. Fried garlic and dried chilies add heat and aroma, while crispy pork rinds are a common topping. The soup is bright red from tomatoes and chilies, and has a rich, savory depth from the fermented ingredients.
Where does Nam ngiao come from?
Nam ngiao comes from the Shan people, who live in Myanmar's Shan State, northern Thailand, and parts of Yunnan, China. It began as a regional specialty but is now a celebrated part of northern Thai cooking, especially north of Phrae Province. The name may come from the Bombax ceiba tree, whose dried flowers are used in the soup, or from an old term for the Shan people. Over time, Nam ngiao became a dish for gatherings and important events in Lanna tradition.
How is Nam ngiao made?
To prepare Nam ngiao, rice noodles are cooked and placed in bowls. The soup base is made by simmering pork or beef with tomatoes, thua nao, and dried Bombax flower cores. Curdled blood is diced and added for texture and flavor. Fried garlic and dried chilies are stirred in for extra heat. The finished soup is ladled over the noodles and topped with pork rinds. Some versions may use shrimp paste instead of thua nao if needed.
