Som Tam
ส้มตำIsaan-style green papaya salad (Som Tam Lao)
Som Tam • ส้มตำFor this Isaan guide, the main version is Som Tam Lao: shredded green papaya pounded with chilli, garlic, tomato, long beans, lime, tamarind and cooked/pasteurised pla ra. It is typically sour, salty and pungent rather than sweet-forward.
Ingredients
10 items- 300 g shredded green papaya
- 2–4 bird’s-eye chillies, or to taste
- 2 garlic cloves
- 50 g long beans, cut into short pieces
- 6 small tomatoes, halved
- 1 small Thai eggplant, thinly sliced (optional but traditional in documented Som Tam Lao)
- 2 tbsp lime juice
- 1 tbsp tamarind water or mild tamarind paste, diluted to taste
- 2 tbsp commercial cooked/pasteurised pla ra
- 1–2 tsp sugar, only as needed for balance
Step-by-Step Method
6 steps- 1
Pound the garlic and chillies in a mortar until roughly crushed.
- 2
Add the long beans and bruise them lightly.
- 3
Add the tomatoes and Thai eggplant, if using, and gently bruise without turning them to paste.
- 4
Add lime, tamarind, cooked/pasteurised pla ra and a small amount of sugar; mix and taste.
- 5
Add the shredded papaya and toss while lightly pounding so the dressing coats the strands.
- 6
Taste again: this Isaan-style version should be sour, salty, spicy and fermented rather than distinctly sweet.
Use a reputable cooked/pasteurised bottled pla ra. If green papaya is unavailable, cucumber/carrot can make a useful salad, but it is an adaptation and no longer the same texture as som tam.
Start with less chilli and pla ra, then adjust; both can be increased after tasting.
Use cooked/pasteurised commercial pla ra. Do not treat raw or inadequately processed fermented fish as equivalent.
- Som Tam Thai: a distinct sweeter style commonly using fish sauce, palm sugar, roasted peanuts and dried shrimp.
- Som Tam Korat: a Korat/Nakhon Ratchasima variation that can combine elements of Thai- and pla-ra-style som tam.
