Full Ingredients

For the Salad

• 1 lb (450 g) green papaya, peeled and shredded into fine strands (about 4 cups)
• 3.5 oz (100 g) long beans or green beans, trimmed and cut into 1-inch pieces
• 1 cup (150 g) cherry tomatoes, halved
• 1/3 cup (45 g) roasted unsalted peanuts, coarsely crushed, plus extra for garnish
• Lime wedges, for serving (optional)

For the Pound-and-Toss Dressing

• 3 garlic cloves
• 2–4 Thai bird’s eye chilies, stemmed (reduce seeds for less heat)
• 2 tbsp (24 g) palm sugar, finely grated
• 3 tbsp (45 ml) fish sauce
• 3 tbsp (45 ml) fresh lime juice
• 1 tbsp warm water (to help dissolve sugar)

Optional but Authentic

• 2 tbsp (15 g) dried shrimp, rinsed and patted dry

Step-by-Step Instructions

Step 1: Prep the papaya and vegetables

Peel the green papaya. Using a julienne peeler, mandoline, or knife technique, shred into fine matchsticks (about 4 cups). Trim and cut the long beans into 1-inch pieces. Halve the cherry tomatoes. Coarsely crush the roasted peanuts. If you want extra crisp papaya, soak the shreds in ice water for 5–10 minutes, then drain and pat dry (optional; add to prep time if using).

Step 2: Pound aromatics

In a large mortar and pestle, add the garlic and chilies. Pound until they break down into a rough, fragrant paste—about 30–45 seconds. Aim for visible bits rather than a smooth puree; those flecks give bursts of flavor.

Step 3: Dissolve the palm sugar

Add the grated palm sugar to the mortar and pound to combine, letting the abrasive garlic-chili paste help dissolve it. Splash in 1 tablespoon warm water and mash until syrupy with no hard sugar bits remaining.

Step 4: Season and bruise beans and peanuts

Pour in the fish sauce and mix well. Add the long beans and half the crushed peanuts (and dried shrimp if using). Pound lightly to bruise the beans without smashing them, about 15–20 gentle hits, while stirring with a spoon to distribute the dressing.

Step 5: Add tomatoes and release their juices

Add the halved cherry tomatoes. Pound very gently—just enough to crack them so they release juices into the dressing. This creates the classic light, savory-sweet brine.

Step 6: Toss in papaya and finish with lime

Add all the shredded papaya. Use one hand to toss with a large spoon while giving occasional light taps with the pestle to help the dressing penetrate. Pour in the lime juice and toss again. Taste and adjust: add a pinch more palm sugar for sweetness, a splash of fish sauce for salt, more lime for brightness, or another chili for heat. Plate immediately, scatter with remaining peanuts, and serve with lime wedges.

Pro Tips

• Use truly green, unripe papaya; it should be firm, pale, and not sweet. Soft or yellowing fruit won’t stay crisp.
• No mortar and pestle? Use a sturdy bowl; mash aromatics with a wooden spoon, and bruise beans and tomatoes in a zip-top bag with a rolling pin.
• Balance is everything: aim for equal parts lime and fish sauce, with palm sugar just rounding the edges. Adjust at the end to your taste.
• Crush peanuts just before serving so they stay aromatic and crunchy.
• For extra crunch, give the papaya a quick ice-water soak, then dry well so the dressing clings.

Variations

• Classic Som Tam Thai with dried shrimp: Add 2 tbsp (15 g) dried shrimp in Step 4 for a savory, briny pop.
• Vegetarian/Vegan: Replace fish sauce with vegan “fish” sauce or 2 tbsp light soy sauce plus 1 tsp mushroom powder; adjust sugar and lime to balance.
• Green mango swap: Use firm green mango in place of papaya for a tangier, fruitier version.

Storage & Make-Ahead

Som Tam is best eaten immediately while crisp. For make-ahead, keep components separate: shredded papaya (well dried) and cut long beans can be refrigerated up to 24 hours; store the dressing (without lime) up to 2 days. Toss with tomatoes, lime juice, and peanuts just before serving. Leftover dressed salad will soften; refrigerate up to 1 day in an airtight container, knowing it will lose crunch.
