Khao Soi, and the Eight Other Northern Dishes You Should Eat
Khao soi is the dish Chiang Mai is actually famous for, and the version in the tourism brochure is a coconut soup with a photograph on it.
Northern Thai food is a genuinely separate cuisine from the rest of the country and almost nobody outside Chiang Mai knows that. The difference is the influence of Shan, Burmese and Lao cooking, and the result is a menu with more pork, more vinegar, more chilli, and much less sweetness than anything in Bangkok.
It is also a great deal better than the average visitor gets, because the famous dish is being sold to people who do not know what it should look like.

Khao soi, the actual dish
A dry curry noodle, not a soup. The bowl is wheat noodles stir-fried with a thick, meaty, oil-sheened curry paste, and the broth is served in a small pot on the side, separate, for you to add as much or as little as you want. This separation is the tell. If the curry and the broth arrive already combined, you are eating a different thing that also happens to be called khao soi.
The meat is usually beef or pork, and it should be a single large piece, not diced. A whole thigh, simmered until it falls apart, sitting on top of the noodles. The pieces of meat you find in a Chiang Mai version should be tender enough that a spoon cuts them without resistance.
Topped with a crispy noodle nest, pickled mustard greens, raw shallots, a boiled egg, and a wedge of lime. The lime is not decorative. The dish is meant to be finished with a hard squeeze, which cuts the oil and sharpens the whole thing. Anyone eating khao soi without lime is having a muted version of the food.
It costs 30 to 60 baht. In the old city, at a shop with a wok and a queue. In a restaurant with English menus and air conditioning, expect 150 to 300 and a worse dish.
Where to eat it
Walk away from Khao Soi Road. That street is named after the dish and it is a row of shops competing on volume, and most of them are fine. The better khao soi in this city is in a soi, or in a market, or at a shop with no English on the menu and a queue of people on their lunch break.
Go before 11am or after 7pm. By 1pm the good shops have sold out and what is left has been sitting, because this is a dish that is cooked in small batches throughout the day and not held over.
Sai ua, and why it should alarm you slightly
A northern sausage, heavily spiced, usually pork, packed into a casing. This is the dish that surprises people, because it looks like something that should not be a sausage and is somehow a sausage.
Order it grilled and sliced with a small bowl of nam prik ong on the side, which is a dip made from dried, charred, pounded chillies with pork fat and toasted rice. It is genuinely hot, it is genuinely delicious, and it is the best thing to eat with your hands in northern Thailand.
Look for a shop that grills it to order. The ones with a pile pre-cooked in a warm cabinet are not what you want.
Nam prik ong, on its own
The dip from the previous paragraph deserves its own entry, because it is the defining flavour of this region and it appears in a dozen dishes. Dried red chillies, charred over fire, pounded with garlic, shallots, fried shallots, and pork fat until it is a dark, brick-coloured paste with visible grain.
It is not smooth and it should not be. A smooth red paste is a southern or central Thai nam prik, and if you have been eating those and then order ong expecting the same thing, you will be surprised by the texture. Take it with vegetables, with boiled pork, with sai ua, with sticky rice.
There is a milder version, nam prik noom, which is roasted green chillies. Ask which one you are getting if you care.
Khao kan jin
Northern sticky rice, steamed in a small pot with a pork blood cube and a piece of fried pork rind, and served with a small bowl of jeow nam, a pork-based dip flavoured with garlic and vinegar. It looks like a small, pale, unappetising mound and it is one of the best things in the country.
Breakfast food. The best version is a cart in the morning, and the pork blood is what gives it the colour and the flavour, so a version without it is missing the point.
Gai yang, and the grilled chicken that is everywhere
Northern gai yang is different from the southern version. Less sweet, more charred, and it is usually marinated with a paste rather than a sugary glaze. The northern version is more aggressively seasoned and the skin is meant to be properly blackened in places.
Ask which one you are getting if you care about sweetness, because the same name covers two quite different dishes.
Northern sausage larb, or the salad with a reputation
Larb exists throughout the region in many forms. The northern version is a minced pork salad, heavily flavoured with vinegar, lime, chilli and toasted rice powder, served with vegetables, and it is the dish that makes people claim northern food is too hot.
It is not hot in the way a southern som tam is hot. It is hot the way vinegar is hot. The sharpness comes through first, the chilli second. The northern version uses less sugar and more acid than anything you will have eaten elsewhere in Thailand, and if you order it expecting the sweetness of a central Thai salad you will be surprised in a completely different direction.
Order this before anything else if it is your first northern meal
Nam prik noom with grilled pork and sticky rice. Milder than the ong, broadly approachable, served with the greens and the chillies on the side so you control the heat, and it teaches you what this cuisine actually is: strong seasoning, fresh herbs, a lot of chilli kept separate, and vinegar as a primary flavour rather than an afterthought.
Two practical things
The northern portion sizes are generous and the spice is genuinely separate. Almost everything arrives with its chilli on the side, which is a real advantage if you are not a chilli person. Ask for mai phet phra, not spicy hot, and the cooking chilli will be reduced.
Do not skip dessert in the north because of the reputation for spice. Khao taeng, a steamed sticky rice cake in banana leaf flavoured with coconut and palm sugar, is on every menu in Chiang Mai and is the correct way to finish a northern meal. It is not spicy. It is better than the version in the south.
