Khao Yam (ข้าวยำ)

The Salad That's Really a Breakfast

ข้าวยำ is the southern Thai dish Wongnai introduces by telling you to forget the Korean rice bowl: rice, raw vegetables and a sauce to bind them, but built from the herbs of the south and dressed with nam budu — fermented anchovy sauce, the region's answer to pla ra — simmered with lemongrass, galangal and kaffir lime leaves until it smells like the market at dawn.

The vegetable set is flexible by design. Wongnai's Poondang says it plainly: whatever local herbs are on hand, sliced fine so the sauce clings. Cha phlu leaves, lemongrass and kaffir lime are the constants; gotu kola, torch ginger flowers, sator beans and sour mango come and go with the season. The Samphaotong curry-paste house of Satun lists the dish as a breakfast, eaten with boiled egg, pea aubergine and cashew leaf shoots.

Then there's the rice. Poondang crushes fresh butterfly-pea flowers into the cooking water for a blue bowl; the food-science blogger at Mccview steams his with butterfly-pea and turmeric waters for blue and yellow halves; Kapook's Songkhla cook doesn't bother — plain rice, because the spectacle in her version is elsewhere: rice vermicelli stir-fried with dark soy and broken rice crackers, so the sauce has something to cling to and something to crunch.

The Recipe (home version, from Wongnai's Poondang)

The weighed version (Mccview): 200 g rice, 20 g each dried shrimp and roasted coconut, 60 g pomelo, 40 g sour mango, 40 g each bean sprouts and cucumber, 30 g long beans, 20 g lemongrass — with a 240 g budu sauce simmered with 120 g palm sugar, shallots, lemongrass and galangal. The health swap (Wongnai's ปากน้ำเมี่ยน): brown jasmine rice and a sweet shrimp-paste sauce (1 tbsp kapi, 90 g fried salted mackerel, palm and white sugar, makrut juice) instead of budu.

The Method

1. The blue rice. Jasmine rice rinsed, water in, butterfly-pea flowers crushed into the pot until the water turns blue, then cooked like any rice.
2. The budu. Budu into a pot with lemongrass, kaffir lime leaves, galangal, shallots and the salted king mackerel; medium heat until reduced by a quarter, palm sugar in, a short simmer, then strain.
3. The shredding. Every herb and vegetable sliced as fine as patience allows — the sauce clings to fine cuts, and a coarse chop stays dry.
4. The assembly. Rice on the plate, the shredded vegetables, dried shrimp, roasted coconut and chilli powder over it, budu spooned across, lime squeezed, everything tossed at the table.

Where Thai Sources Disagree

How Western Versions Get It Wrong

• Making it a cooked salad. Wongnai's distinction matters: Korean bibimbap vegetables are blanched or fried; khao yam's herbs are raw, sliced fine. Cooking the herbs kills the dish.
• Substituting fish sauce for budu. Budu is fermented anchovy, reduced with galangal and lemongrass — fish sauce is salt with a different smell. The sauce is the identity of the dish.
• Skipping the roasted coconut. Freshly roasted, it's the richness the salad is built around; most Thai cooks roast their own and refuse the stale, pre-toasted stuff.
• Chunky vegetables. A coarse chop doesn't hold the sauce. The fine slice is the technique.
• Dressing it like a vinaigrette salad. The budu goes on at the table, lime and chilli powder to taste, and everything is tossed together — the rice included.

UK Ingredient Notes

• Budu sauce: bottled, at Thai grocers — Sinthorn Adulyaphon (Songkhla) is the brand Thai cooks name.
• Cha phlu (wild betel) leaves: fresh bunches at Thai grocers; frozen as fallback.
• Butterfly pea flowers: dried, from Thai grocers and online — steep in the rice water for the same blue.
• Salted king mackerel (ปลาอินทรีเค็ม): tinned or vacuum-packed at Asian grocers.
• Torch ginger flowers, sator beans, gotu kola: frozen or jarred at Thai grocers — optional, the salad survives without them.
