Nam Jim Jiao Sauce

A traditional Isan Thai sauce that is bright, salty, sour, and spicy, thickened with toasted glutinous rice powder and served with grilled meats, sticky rice, or crisp vegetables.

Ingredients

  • 45 ml good-quality Thai fish sauce
  • 60 ml fresh lime juice
  • 30 g Thai tamarind paste
  • 18 g Thai palm sugar
  • 2 tbsp toasted glutinous rice powder
  • 2 tsp dried Thai chili flakes
  • 40 g fresh Asian shallots
  • 2 sprigs fresh scallion
  • 4 sprigs fresh cilantro

Method

  1. Prepare the toasted glutinous rice powder if it is not ready already: see the prepared component. It must be cool before it goes into the sauce, or it will absorb the liquids too quickly and thicken unevenly.
  2. Finely slice the shallots. Cut the scallion into thin rounds and finely chop the cilantro. The pieces should remain visible but be small enough to distribute through every spoonful.
  3. In a bowl, combine the fish sauce, lime juice, tamarind paste, and palm sugar. Stir until the sugar has completely dissolved; the sauce should be glossy, fluid, intensely fragrant, and distinctly salty-sour.
  4. Add the dried Thai chili flakes. Stir, then let stand for a few moments so the chili rehydrates slightly and colors the sauce amber-red.
  5. Stir in the shallots, scallion, and cilantro. Mix gently so you do not crush the herbs; the sauce should remain fresh, lively, and aromatic.
  6. Add the toasted glutinous rice powder last. Stir just enough to hydrate it: the texture should become slightly grainy and spoon-coating, with a clear toasted aroma, without turning into a compact paste.
  7. Taste and adjust in the traditional spirit: add more lime if the sauce seems heavy, a little fish sauce if it needs salt, or a touch of palm sugar if the acidity is too dominant. Serve at room temperature, ideally with grilled meat, sticky rice, or raw vegetables.
