Chiang Mai, like many cities, has food items that are specialties of the area. While there are plenty of restaurants to satisfy the tourist's palate, there are certain local items not to be missed.
One of these dishes is Northern Thai Khao Soi (curry noodle soup). The mild thick curry soup is usually served with chicken, or some other meat, and made with egg noodles. Originally from Burma, it has been adapted and modified by the Thais and has become a staple in Chiang Mai.
It generally contains red curry paste, phom kari (mild Thai yellow curry powder), garlic, coconut milk, ground pork, turmeric, sugar, lime juice, and stock. Accompaniments include chopped shallots, pickled cabbage (phak kaat dong) and lime wedges.
Sausages are quite popular in Thailand but Sai Oua is unique to Northern Thailand. It's a drier sausage made with pork, garlic, coriander, lime juice, lemon grass, galangal powder, shallot, shrimp paste, and chili peppers.
I would never recommend making sausages on your own, unless you're like our friend Pic back home who does it routinely. And he does a killer Sai Oua.
It's all safe to eat and always a great bargain. Above is a street vendor dishing up Pad Thai for a mere 20 baht (65 cents) per serving.
So when in Thailand, and especially in Chiang Mai, try the street food.
