Thai cuisine is among the most distinctive in Asia: vivid aromas, a simultaneous balance of hot, sour, sweet and salty in a single dish, and an abundance of fresh herbs and spices. On Samui, tourists often encounter adapted menus — but authentic Thai food is here too, if you know what and where to look for.

Core Principles of Thai Cooking

Thai food is built on four simultaneous flavours: spicy (chilli), sour (lime, tamarind), sweet (palm sugar), and salty (fish sauce, soy sauce). No single element should dominate — a well-made dish balances all four. Freshness of ingredients is critical; many dishes are cooked in five to ten minutes, to order.

Dishes Worth Trying

Soups

  • Tom yam — a hot-and-sour soup with lemongrass, galangal, kaffir lime leaves, and mushrooms. Two main versions: tom yam kung (with prawns) and tom yam gai (chicken). Sour, spicy, aromatic — the classic.
  • Tom kha — a milder coconut-milk version of the same aromatic base. Less spicy than tom yam.
  • Gaeng jued — clear soup with tofu, minced meat, and glass noodles. Neutral in flavour — a good choice if you dislike spice.

Curries

  • Green curry (gaeng keo wan) — the spiciest, made with coconut milk, green chilli, Thai basil, and aubergine.
  • Red curry (gaeng phet) — less spicy, versatile. Served with chicken, duck, or beef.
  • Yellow curry (gaeng gari) — the mildest, with turmeric and potato. Closest in flavour to Indian curry.
  • Massaman curry — a southern Thai variant with peanuts and potato. Slightly sweet, with Indian-influenced spicing.

Stir-fries

  • Pad thai — stir-fried rice noodles with egg, bean sprouts, peanuts, and lime. With prawns or chicken. One of Thailand's most popular dishes.
  • Pad kra pao — stir-fried minced meat (chicken, pork, or beef) with holy basil and chilli. Served with rice and a fried egg on top.
  • Fried rice (khao phat) — a quick everyday dish with egg and a choice of meat or seafood.

Salads

  • Som tam — spicy green papaya salad with tomato, peanuts, fish sauce, and chilli. A national dish.
  • Laab — a minced meat salad with fresh mint, shallots, and toasted rice powder. Very spicy.

Managing Spice

Thai food is spicy by default. You can adjust the heat level when ordering:

  • "Mai pet" — no spice
  • "Pet nit noi" — a little spice
  • "Pet pet" — very spicy (for enthusiasts)

Tourist restaurants in Chaweng and Lamai often tone the heat down considerably. Local cafés stay closer to traditional recipes.

Key Ingredients to Know

Fish sauce (nam pla) — the salty backbone of most Thai dishes. Galangal — a cousin of ginger with a resinous, earthy aroma used in curries and soups. Lemongrass — the citrus-scented stalks essential to tom yam. Kaffir lime — leaves and zest add a floral note. Thai basil — spicier and more pungent than European basil; essential in pad kra pao.

With this reference, you can order deliberately at any Thai restaurant — and enjoy a known dish rather than a guessing game.
