Yam is the Thai family of dressed salads — distinct from som tam (pounded in mortar) and Western salads (tossed in pre-made dressing). The dressing is built separately and balanced before meeting the main ingredient. Protein is often warm and dressed immediately so it absorbs flavour. Fresh herbs tossed through at the last moment.
Dressing built from fish sauce, lime juice, sugar, and chillies — mixed and tasted separately before it touches the salad. It should taste slightly too intense on its own — it mellows on the ingredients. Protein dressed while still warm — heat opens the surface. Fresh herbs torn not chopped at the last moment. For larb: toasted rice powder (khao khua) is the signature element.
For toasted rice powder: dry toast sticky rice in wok over medium heat, shaking constantly, 8–10 minutes until deep golden. Cool completely, pound to coarse sandy powder. Make extra — keeps for weeks. For yam nua: grill beef to medium-rare, slice thin while hot, dress immediately. Toss with shallots, mint, cilantro, chillies, and toasted rice powder just before serving.
Dressing too mild — yam dressings should be punchy. Dressing the salad too early — herbs wilt. Dressing cold protein. Forgetting textural elements — toasted rice powder, fried shallots, roasted cashews. Using sweet chilli sauce instead of building from scratch. Chopping herbs instead of tearing.
