Chiang Mai (Lanna)

Overview

Chiang Mai, the capital of the former Lanna Kingdom, anchors a distinct culinary tradition that differs markedly from central Thai cuisine. Lanna food is characterized by milder spicing, a preference for sticky rice over jasmine rice, and the use of ingredients like turmeric, ginger, and bitter herbs. The cuisine reflects the region’s mountainous terrain, cooler climate, and historical trade routes with Burma, Laos, and China. Dishes often feature pork, river fish, and foraged greens, with a notable absence of coconut milk in many savory preparations. Fermented foods, such as naem (sour sausage) and pla ra (fermented fish), are common, as are grilled meats and Burmese-influenced curries.

Geography and pantry

Chiang Mai lies in a valley surrounded by mountains in northern Thailand. The cooler climate allows for the cultivation of temperate vegetables like cabbage, tomatoes, and strawberries, as well as local herbs such as phak waan (sweet leaves) and phak bung (morning glory). Sticky rice is the staple grain, eaten by hand with dips and curries. Key ingredients include turmeric, ginger, garlic, shallots, and dried chilies. Pork is the primary meat, used in sausages, curries, and grilled dishes. River fish, such as pla chon (snakehead), are common, and fermented fish (pla ra) adds umami to many dishes.

Signature dishes

• Khao Soi — Curry noodle soup with crispy and boiled egg noodles in a coconut-based broth, typically with chicken or beef, garnished with pickled mustard greens and shallots.
• Sai Oua — Grilled pork sausage seasoned with lemongrass, galangal, turmeric, and kaffir lime leaves, served with fresh vegetables and sticky rice.
• Nam Prik Ong — A spicy tomato-based pork dip served with raw vegetables and sticky rice, often eaten as a snack or light meal.
• Gaeng Hang Lay — A Burmese-influenced pork curry with ginger, turmeric, tamarind, and peanuts, slow-cooked until tender.
• Laap Kua — A dry-fried minced pork salad with roasted rice powder, lime juice, and fresh herbs, distinct from the raw laap of Isan.
• Khao Niao Mamuang — Mango with sticky rice, a dessert of glutinous rice cooked in coconut milk and served with ripe mango slices.
• Khanom Jeen Nam Ngiao — Fermented rice noodles in a pork and tomato broth, topped with blood tofu and crispy pork rinds, a specialty of northern Thailand.

Cooking techniques

Grilling over charcoal

Many Lanna dishes, such as sai oua and grilled meats, are cooked over low charcoal fires, imparting a smoky flavor. This technique is central to street food and home cooking alike.

Fermentation

Fermentation is key to Lanna cuisine, producing ingredients like pla ra (fermented fish), naem (sour pork sausage), and khao mak (fermented rice dessert). These add depth and umami to dishes.

Pounding in a mortar

Curry pastes, dips like nam prik ong, and salads are traditionally made by pounding ingredients in a large stone mortar. This releases essential oils and creates a coarse texture.

Sub-regions and styles

• Chiang Rai — More Burmese influence, with dishes like khao soi often made with a lighter broth.
• Mae Hong Son — Strong Shan (Tai Yai) influence, featuring Burmese-style curries and fermented tea leaf salad (lahpet).
• Lamphun — Known for longan fruit and a tradition of sweet snacks like khao lam (sticky rice in bamboo).
• Nan — Mountainous region with foraged ingredients, such as bamboo shoots and wild mushrooms, used in soups and curries.

In Los Angeles

Lanna cuisine has a modest but growing presence in Los Angeles, primarily in Thai Town (Hollywood) and the San Gabriel Valley. Restaurants like Northern Thai Food Club (formerly in Thai Town) and Luv2Eat Thai Bistro offer dishes such as khao soi and sai oua. However, many Lanna specialties are less common than central Thai dishes. The diaspora from northern Thailand is smaller than from other regions, so Lanna food is often found in restaurants that serve a broader Thai menu.

Diaspora context

Northern Thai cuisine has spread primarily through Thai diaspora communities in the United States, Australia, and Europe. In the US, cities with significant Thai populations, such as Los Angeles, New York, and San Francisco, have pockets of Lanna restaurants. The cuisine is also found in Myanmar (Burma) and Laos due to historical and cultural ties, particularly in Shan State and Luang Prabang.
