Nam Ngiao — Northern Pork and Tomato Noodle Soup / น้ำเงี้ยว

Northern Thai (Shan/Lanna) — the dish reflects the Shan State (Burmese) cultural influence on Northern Thai cuisine; particularly associated with Mae Hong Son province

Nam ngiao is the defining noodle soup of Northern Thailand — a richly flavoured broth made from pork ribs, dried cotton seed (ngiao flowers, Bombax ceiba), dried blood cake, and tomatoes with a paste of dried chillies, galangal, shallots, and fermented soybean. The dish is specific to the Shan/Northern Thai cultural corridor and is available throughout Chiang Mai and Northern province noodle shops. The dried cotton flower (dok ngiao) is the ingredient that most identifies this soup — it provides a slight bitterness and a distinctive character that cannot be replaced. The broth is deep red-orange from the tomato and dried chilli, and the accompaniment is either fresh rice noodles or dried noodles.

Nam ngiao represents the distinct food culture of the Shan-influenced North — its dok ngiao bitterness, tomato-pork richness, and deep red colour are unlike any Central Thai soup and demonstrate the North's culinary independence.
