A bold Northeastern Thai (Isaan) salad that swaps fermented fish sauce for pungent whole fermented crabs, giving the classic green papaya salad an intense umami punch. Each bite balances fiery chilies, tangy lime, sweet palm sugar, and the funky depth of briny crab. Serve with sticky rice and grilled chicken for an authentic Thai meal.

Ingredients
For the salad base
- 1 medium green papaya (about 2 lb), peeled and finely shredded
- 8 green long beans, trimmed and cut into 2-inch pieces
- 1 small ripe tomato, cut into thin wedges
- 1/4 cup loosely packed Thai basil leaves
- 2 tablespoons dry-roasted unsalted peanuts, lightly crushed
For the dressing
- 3 Thai bird's eye chilies, smashed
- 3 cloves garlic, peeled
- 2 tablespoons cleaned fermented crab (poo fer), meat and roe reserved
- 2 tablespoons fresh lime juice (about 2 limes)
- 1 tablespoon shaved palm sugar
- 1 1/2 tablespoons Thai fish sauce
- 1/2 teaspoon Thai chili powder (prik pon, optional)
Directions
- Place the smashed chilies, garlic, and a pinch of palm sugar in a large clay mortar and pestle; pound with a circular motion until a coarse paste forms, about 30 seconds.
- Add the cleaned fermented crab pieces and gently bruise them with the pestle to release the briny juices into the paste, taking care not to over-shred them.
- Pour in the lime juice, fish sauce, remaining palm sugar, and chili powder; stir with a spoon until the sugar fully dissolves, then taste and adjust with more lime for sourness or fish sauce for saltiness.
- Add the long beans and tomato wedges to the mortar and lightly pound 3 to 4 times, just enough to crack the beans and bruise the tomato without turning them to mush.
- Toss in the shredded green papaya and basil leaves, then use a large spoon to fold everything together until the papaya is evenly coated and slightly softened but still crunchy, about 1 minute.
- Spoon the salad onto a plate, mounding it slightly, then scatter the crushed peanuts over the top. Serve immediately at room temperature alongside sticky rice or grilled meats.
Cook’s Notes
- Choose a green papaya that is firm and pale green with no yellow blush; ripe yellow papaya will turn mushy and overly sweet.
- Fermented crab (poo fer) is intensely salty on its own, so always taste the dressing before adding extra fish sauce.
- Use a clay mortar instead of a metal one for the most authentic flavor release and to avoid reacting with the lime juice.
- Adjust the number of chilies to control heat; remove seeds for a milder salad or add more for extra fire.
- This salad is best eaten within 10 minutes of mixing so the papaya stays crisp and vibrant.
- Store leftover fermented crab submerged in its brine in a sealed jar in the refrigerator for up to 3 months.
