Pounding
Stone-mortar bruising that builds Thai curry pastes layer by layer.
Traditions
The granite-and-pestle method predates Thai-Lao kingdoms; documented in Sukhothai-era cookery notes, the kaeng paste tradition is what distinguishes mainland Southeast Asian cuisine from its Indian-curry inspiration.
What happens
Pounding in Thai cooking starts with the granite khrok hin — a heavy mortar that bruises rather than chops. Galangal goes in first, then chilies, lemongrass, makrut lime peel, shrimp paste, garlic, in roughly that order. Each ingredient is broken down before the next arrives, so its oils are released into the paste rather than sitting on top. The rhythm is wrist, not arm; the goal is a paste that smells louder than the sum of what went in. Without pounding there is no real Thai curry — a blender mince produces a watery sambal, not a perfumed kaeng.
