Authentic Som Tam Recipe: Pounded Thai Green Papaya Salad
Master this authentic som tam recipe at home. Learn to pound green papaya, long beans, and lime in a clay mortar for a perfectly bruised, spicy, and sour Thai salad.
A proper som tam recipe is less about the assembly and more about the technique of bruising the ingredients to extract their essential oils. This vibrant Thai green papaya salad relies on a heavy clay mortar and a wooden pestle to gently crush the components rather than just tossing them, ensuring every shred of fruit is saturated with flavor.
To make an authentic som tam thai, you need the specific balance of funk from fish sauce, sharp acidity from lime, and the earthy sweetness of palm sugar. By pounding the garlic, chilies, and dried shrimp first, you create a pungent base that transforms simple raw vegetables into a complex, addictive side dish that hits every part of your palate.
Ingredients
The Salad Base
- 2 cups (225g) green papaya, peeled and shredded into long julienne
- 4-5 yardlong beans (or green beans), cut into 2-inch pieces
- 1/2 cup (75g) cherry tomatoes, halved
- 2 tablespoons roasted unsalted peanuts
- 1 tablespoon dried shrimp, rinsed
The Dressing & Aromatics
- 2 cloves garlic, peeled
- 2-4 bird's eye chilies (adjust to your spice preference)
- 2 tablespoons palm sugar, finely chopped
- 2 tablespoons fish sauce
- 2 tablespoons fresh lime juice
- 1/2 lime, cut into small wedges
Instructions
- 1
Place the garlic cloves and bird's eye chilies into a large clay mortar and pound with a wooden pestle until the garlic is crushed and the chilies are broken into small pieces.
- 2
Add the dried shrimp and pound briefly to break them down slightly, releasing their salty, umami aroma.
- 3
Add the chopped palm sugar to the mortar and pound until it dissolves into a thick paste with the garlic and chilies.
- 4
Toss in the yardlong beans and pound them just enough to bruise and crack them, which allows the dressing to penetrate the skins.
- 5
Add the fish sauce, lime juice, and the actual lime wedges to the mortar; stir with a large spoon while lightly pounding to emulsify the palm sugar into the liquid.
- 6
Add the cherry tomatoes and pound very gently, just enough to release their juices without obliterating the skins.
- 7
Add the shredded green papaya to the mortar. Use the pestle to pound the papaya while simultaneously using a large spoon in your other hand to flip and toss the salad from the bottom up.
- 8
Continue pounding and tossing for about 30 seconds until the papaya is slightly bruised and flexible, appearing translucent from the dressing.
- 9
Add the roasted peanuts and give the salad one final toss with the spoon.
- 10
Transfer the som tam to a plate and serve immediately, preferably with a side of sticky rice and raw cabbage wedges.

Tips
- → Use a clay mortar and wooden pestle if possible; a granite mortar is too heavy and will turn the delicate papaya into mush.
- → If you cannot find green papaya, a very firm under-ripe green mango or even shredded kohlrabi makes a decent substitute.
- → To get the best texture, shred the papaya by hand using a sharp knife to make long vertical cuts, then shaving off the layers, rather than using a box grater.
- → Always taste your dressing before adding the papaya. It should be a punchy balance of salty, sour, and sweet—adjust with more fish sauce or lime as needed.
FAQ
How do I keep the papaya crunchy?
Soak your shredded papaya in a bowl of ice water for 10 minutes, then drain and pat it very dry before pounding. This shocks the fibers and ensures a crisp bite.
Can I make this recipe vegan?
Yes, you can substitute the fish sauce with a high-quality vegan fish sauce or a light soy sauce mixed with a pinch of salt, and simply omit the dried shrimp.
Why does my som tam taste bland?
You likely didn't pound the ingredients enough. The magic of a som tam recipe is in the bruising; if the papaya isn't slightly crushed, the dressing just sits on the surface instead of soaking in.
