Food

Four kitchens, not one menu

Central Thai cooking is the diplomatic one: coconut milk, palm sugar, the green and red curries, tom yum, and a deliberate balance no single flavour is allowed to win. It travelled abroad because it flatters everybody. Isaan food, from the north-east, is the opposite — almost no coconut, aggressive sour-salt-chilli, grilled meat, sticky rice eaten with your right hand, and pla ra fermented fish underneath more of it than menus admit. Som tam, laab and grilled chicken is the national street trinity and it is Lao by ancestry. Start with Khon Kaen’s night market, which is the region cooking for itself.

Northern (Lanna) food is the mildest and the most Burmese-adjacent: khao soi’s curried noodles, sai ua herb sausage, nam prik ong and nam prik num with vegetables and pork crackling, and sticky rice again. Chiang Mai mornings is the practical way in. Southern food is the hottest in the country and the least compromised for visitors: turmeric-yellow curries, gaeng som, khao yam rice salad, stink beans, and a Malay-Muslim strand that gives you roti, massaman and beef where the rest of the country reaches for pork. Six essential southern dishes covers the canon; Nakhon Si Thammarat is where to eat it.

The flavour logic (and why your first plate tasted flat)

Thai cooking builds every dish from a small number of axes — salty, sour, sweet, bitter and hot — and the skill is the ratio, not the ingredient list. Our guide to the five tastes explains why fish sauce does the work salt does in European cooking, why lime and tamarind are not interchangeable, and why sugar in a savoury dish is a structural choice rather than a sweet tooth.

The practical consequence sits on the table. A noodle shop gives you a caddy of four condiments — sugar, dried chilli flakes, chilli in vinegar and fish sauce — and you are expected to use them: the bowl arrives deliberately under-seasoned so you can tune it. If a plate of noodles tastes like nothing, that is not a bad stall, that is an unfinished dish. Away from noodles, the equivalent is prik nam pla, the saucer of chilli in fish sauce that comes with rice plates.

Ordering street food without getting the tourist edit

Pick the stall doing one thing. A cart with a single dish, a queue of office workers and visible turnover is a better bet than a restaurant with photographs of everything; the food is fresher because it moves, and the cook has no other job. Eat where the pot is emptying, roughly 11am to 1pm and after 6pm, rather than at 3pm when it has been sitting.

On money: in most of the country a street plate of pad kaphrao or a bowl of noodles runs about 50–70 baht, central Bangkok pushes that to 60–90, a mall food court sits around 80–150, and a sit-down local restaurant dish is 120–250. Prices on a board are the prices; markets do not haggle over food.

On heat: mai phet means not spicy and phet nit noi means a little spicy, and both are frequently interpreted as “spicy, but for a foreigner”, which in the south is still very spicy. If you genuinely cannot eat chilli, say mai sai phrik — do not add chilli — because it asks for an ingredient to be left out rather than a judgement call. Ask for mai sai pla ra in Isaan som tam if fermented fish is not for you.

Fruit and sweets, by season

Fruit here is seasonal in a way supermarket shopping trains you out of noticing, and turning up in the right month is the difference between a good mango and a revelatory one. Mango season peaks March to May, durian runs roughly May to August, mangosteen and rambutan overlap through the middle of the year, and longan lands in the northern summer. Our month-by-month fruit calendar is the one to check before you go, and the grammar of Thai fruit covers how to buy it and how to ask.

Dessert deserves better than the mango sticky rice every hotel breakfast serves. Thai desserts beyond mango sticky rice gets you to the pandan, palm sugar and coconut end of the repertoire — and to the egg-yolk sweets a Portuguese cook introduced to the Ayutthaya court in the seventeenth century.

Markets and neighbourhoods worth travelling for

The best eating in Thailand is organised by market, not by restaurant. Khon Kaen and Nakhon Si Thammarat are the two provincial night markets we send people to first. Amphawa in Samut Songkhram does grilled river prawns from boats on a weekend evening, an hour and a half from Bangkok. And in the city itself, Ari is where Bangkokians actually spend a weekend: old shophouse noodle shops and third-wave coffee on the same soi.

The old, the royal and the reconstructed

“Royal Thai cuisine” is the most abused phrase on a Bangkok menu, and most restaurants using it are betting you cannot tell. The real tradition — palace cooking, obsessive knifework, carved fruit, milder chilli, dishes assembled rather than stir-fried — is a genuine thing worth eating once. Ahan boran traces where the old recipes come from and what has been reconstructed rather than remembered, and our review of Luk Kaithong at One Bangkok is us paying our own bill to test one of the mall versions against the claim.
