Khao soi, also known as Chiang Mai Noodles, is a rich and creamy chicken and egg noodle dish originating from Thailand's northwest region. It's a staple of Northern Thai cuisine, but differs from other dishes in the region by incorporating non-local ingredients like coconut milk and egg noodles, includes pickled mustard, shallots, and lime. Perfectly pairing with refreshing Thai tea lemonade.
