What is Som Tum?
In English, Som Tum and Som Tam both refer to ส้มตำ, the name commonly used for green papaya salad. Som points to sourness and tam describes pounding. The technique also appears in Thai salads made with cucumber, fruit and other ingredients. T2 T3 T7
Green papaya salad is part of Lao and northeastern Thai food traditions and is eaten across Thailand. Som Tum Thai is one style. Its lime, sugar and fish sauce sit alongside dried prawns and roasted peanuts, while other versions use fermented fish or salted crab. T1 T2 T5 T7 E3
See our guide to Thai food and flavours for more dishes and the ingredients that distinguish them.

Som Tum Thai home recipe
Adapted from the one-portion recipe in MICHELIN Guide Thailand. The quantities and pounding order follow that recipe. Cherry tomatoes and peeled garlic are practical choices. The optional lighter chilli level and the suggestion to add the fish sauce gradually are adjustments for home cooks. T1
Use a deep mortar, a wooden pestle, a spoon, a chopping board and a knife or a julienne peeler. A tablespoon is 15 ml. Wash and drain the produce before preparing it. E1 U1
Ingredients for one portion
- 80 g shredded unripe green papaya and 10 g carrot, cut into fine strips
- 4 fresh red Jinda chillies or bird’s-eye chillies, or fewer for less heat
- 2 peeled Thai garlic cloves
- 4 to 5 yardlong beans, cut into short pieces, and 2 cherry tomatoes, halved
- 4 lime wedges, squeezed for their juice
- Up to 2 tbsp fish sauce (30 ml), added to taste
- 1 tbsp palm sugar and ½ tbsp brown sugar
- 15 g dried prawns and 20 g roasted peanuts, with some peanuts reserved for serving
Method
- Prepare the vegetables. Peel and deseed the papaya and cut it into firm shreds. Set it aside with the carrot. Cut the beans and halve the tomatoes.
- Crush the aromatics. Roughly pound the chillies and garlic. Add most of the roasted peanuts and tap until they crack.
- Bruise and dress. Add the beans and tomatoes and press lightly. Mix in the palm sugar, brown sugar, lime juice and part of the fish sauce. Work the sugar into the liquid and taste before adding the rest of the fish sauce.
- Turn the papaya through. Add the papaya, then the carrot. Turn the shreds with a spoon while tapping gently with the pestle. Stop when the dressing coats the shreds and they still hold their shape.
- Finish on the plate. Add the dried prawns and the reserved roasted peanuts. Serve once assembled.

How to keep green papaya salad crunchy
Choose firm, pale-fleshed unripe papaya and cut it into shreds with enough thickness to keep their bite. A julienne peeler is convenient. If the tool produces very fine shreds, cut the papaya into sturdier strips on a board. E1 E2
| Look for | What to do |
|---|---|
| Beans just split | Tap them early so they bruise before the papaya goes in. |
| Tomatoes still in pieces | Press enough to release a little juice, then move on. |
| Papaya shreds still intact | Turn and tap gently at the end, then stop when the dressing is evenly distributed. |
Can you make Som Tum ahead?
Prepare the shreds and the dressing separately. Cover and chill them, then bruise and mix the salad near serving. If you are taking it to share, carry the dressing separately and finish the salad at the table. Keep the finishing peanuts separate until plating. T1 E2 U2
Making it without a mortar
Crush the garlic and chilli with clean equipment, bruise the beans lightly and mix the dressing in a bowl. Toss it through the papaya and tomatoes just before serving. The bowl method is a practical adaptation with a different texture. T6 U1
Ingredients, substitutions and seasoning
| Ingredient | What it does | What to check |
|---|---|---|
| Green papaya | Gives the salad its firm shreds | Buy unripe papaya. Green mango makes a sharper-tasting variation. |
| Yardlong beans | Give a fresh, firm bite | Ordinary green beans are an option in a home adaptation. |
| Tomatoes | Release juice into the dressing | Bruise them lightly. Taste the dressing before adding more liquid. |
| Lime, fish sauce and sugars | Bring sour, salty and sweet flavours together | Taste on a shred of papaya and adjust gradually. |
| Fresh chillies and garlic | Bring heat and aroma | Start with less chilli if you prefer a gentler salad. |
| Dried prawns and peanuts | Add savouriness and contrasting textures | Check crustacean and peanut ingredients and handling. |
The balance varies by recipe. KRUA.CO makes a separate dressing with tamarind and adds lime as the salad is mixed. The home recipe above uses the lime and two-sugar combination from its named source. T1 T4 E2
Som Tum Thai, Pla Ra, Pu and other styles
| Style | What typically distinguishes it |
|---|---|
| Som Tum Thai | A lime, fish sauce and sugar dressing, often with dried prawns and roasted peanuts. |
| Som Tum Pla Ra | Fermented fish seasoning adds a deeper savoury flavour. Other ingredients vary. |
| Som Tum Pu | Salted crab is a feature in this style. Some preparations combine crab and fermented fish. |
| Tum Tang | Cucumber forms the base. |
| Pounded fruit or corn salads | Mixed fruit or sweetcorn gives a different balance of sweetness and texture. |
These names help you choose a style. Ask about the actual ingredients if you have an allergy, especially where fish sauce, fermented fish, crab, dried prawns or peanuts may be used. T1 T2 T7 E3 E4 U3
What to serve with Som Tum
Sticky rice and grilled chicken are a familiar pairing. Fresh vegetables can sit alongside the salad. For a different vegetable side, see our Yum Pak guide for a tossed cucumber and carrot version. T5 T6 C3
