Som Tum Poo Plara
ส้มตำปูปลาร้า
Som Tum Poo Plara is the most intensely flavoured regional variant of green papaya salad — made with raw pickled blue crab and fermented fish (plara) alongside the standard green papaya ingredients.
Cultural Origin
Som Tum Poo Plara is the most pungent Isaan-Lao version of green papaya salad, pounded with salted black field crab and fermented fish sauce (plara). It is the everyday rural salad of the Lao-Isaan cultural belt and is sharply distinguished from the milder Thai-Chinese 'som tum thai' served in Bangkok.
Regional Variants
| Region | How it differs |
|---|---|
| Isaan | The Isaan version is the original, made with plara and salted black crab and very little sugar. |
| Central | Central Thai vendors sometimes serve a milder, sweeter compromise version with reduced plara. |

The most pungent of the papaya salads — fermented fish sauce gives a deep, funky aroma that arrives before the taste does, and the raw crab adds a briny, mineral note rather than sweetness.
How Som Tum Poo Plara Is Made
- 1
Pound aromatics
Garlic and a heavy hand of bird's-eye chilli are pounded first in the mortar.
- 2
Add plara
Fermented fish sauce (plara) is pounded in early so its liquid distributes through the base rather than sitting on top.
- 3
Add crab
Raw pickled crab pieces, shell included, are pounded briefly to release their juices into the dressing.
- 4
Add papaya and beans
Shredded green papaya and long beans are folded in and lightly pounded to bruise them, not pulverise them.
- 5
Balance and serve
Lime juice is added last to balance the salt and funk, and the salad is served immediately without resting.
When It’s Eaten
An everyday rural Isaan dish rather than a tourist-menu item, eaten with sticky rice and often grilled meat; it is the version locals order for themselves rather than the one adapted for visitors.

What people get wrong
Ordering it as a first introduction to som tum — the raw crab and fermented fish sauce make it the strongest-flavoured version by a wide margin, and som tum thai is a better starting point for gauging tolerance.
Where to Try It
Authentic Isaan restaurants and street stalls in northeast Thailand and Bangkok's Isaan food areas.
Tips
- This is not for the timid — the fermented fish sauce (plara) gives it a funky, intensely savoury depth that polarises newcomers. Try the milder som tum Thai first.
