Som tam — green (unripe) papaya salad, pounded in a mortar with fish sauce, lime, palm sugar, dried shrimp, chilli, and tomato — is one of the most technically specific preparations in Southeast Asian cooking: the green papaya must be shredded to a specific width; the ingredients must be combined in the mortar in a specific sequence; and the pounding must be controlled (bruising, not destroying) to produce a salad with structural integrity. Som tam made in a blender is not som tam.
- **The green papaya:** Peeled, seeded, and shredded into matchstick-thin strips — 3–4mm wide, 5–7cm long. A shredder with a specific serrated blade (the traditional tool) produces the correct width; a knife produces strips that are either too thick or unevenly sized. - **The pounding sequence:** 1. Garlic and chilli pounded first to a rough paste — the base aromatics 2. Green beans added and lightly bruised 3. Dried shrimp added — pounded briefly to bruise and begin releasing their flavour 4. Tomato halves added — bruised but not completely destroyed (whole tomato pieces remain) 5. Palm sugar dissolved in the fish sauce and lime added 6. Papaya added — folded and lightly pounded (the pestle is used to bruise, not smash) - **Bruising not smashing:** The papaya strips should be lightly bruised — flexed and cracked slightly to allow the dressing to penetrate, but still holding their shape. Completely smashed papaya produces a wet, soft result.

Correct som tam does not have a dominant note. - **Variations:** - Som tam Thai: with dried shrimp and peanuts (toasted) - Som tam Lao: with pla ra (fermented fish) — much more pungent - Som tam poo: with fermented crab — the most extreme version Decisive moment: The papaya bruising — the single pounding that cracks the surface of each strip. Underbused: the dressing sits on the surface without penetrating. Over-bruised: the strips become soft and watery.
