Kacang Sauce for Gado-Gado

A thick, glossy, slightly coarse Indonesian peanut sauce designed to coat the vegetables, tofu, tempeh, and hard-boiled eggs in traditional gado-gado.

Ingredients

  • 250 g shelled unsalted peanuts
  • 3 tbsp peanut oil
  • 3 cloves fresh garlic
  • 2 pieces Asian shallots or gray shallots
  • 2 pieces long fresh red chilies
  • 1 piece fresh bird's eye chili
  • 55 g Indonesian palm sugar or block coconut sugar
  • 35 g seedless tamarind paste
  • 3 tbsp Indonesian kecap manis
  • 1 tsp Indonesian fermented shrimp paste
  • 1 piece fresh lime
  • 1 tsp fine salt
  • 300 ml water

Method

  1. Toast the peanuts in a wide skillet with the peanut oil over medium heat, stirring constantly. They should turn amber-blond, smell roasted, and crackle gently without darkening. Drain them on paper towels and keep the fragrant oil in the skillet.
  2. Sauté the garlic, shallots, red chilies, and bird's eye chili in the same oil. Keep the heat medium-low: the aromatics should soften, take on a light golden color, and lose their raw smell without burning at the edges.
  3. Pound the peanuts with the sautéed aromatics, palm sugar, fermented shrimp paste, and salt. Use a mortar for a traditional texture: the paste should remain slightly coarse, with very fine peanut pieces visible. If necessary, pulse-blend briefly without turning the mixture into smooth peanut butter.
  4. Thin the tamarind paste with some of the water, then gradually add it to the peanut paste. Mix until you have a thick, golden-brown mass that is softer but still compact.
  5. Transfer to a heavy-bottomed saucepan. Add the remaining water little by little over low heat, stirring regularly with a spatula. The sauce should loosen, gently simmer at the surface, and become glossy; if it starts to stick, lower the heat immediately.
  6. Stir in the kecap manis and cook gently until the sauce heavily coats the spoon. The right cue is that a track drawn with your finger across the back of the spoon remains visible briefly, while the sauce falls slowly in a thick ribbon.
  7. Taste off the heat. Adjust with lime juice for the expected Indonesian balance: roasted peanut first, palm-sugar sweetness next, clear tamarind and lime acidity, and a salty, spicy finish.
  8. Serve warm or at room temperature over gado-gado: crisp blanched vegetables, potatoes, bean sprouts, cabbage, long beans, tofu, tempeh, and hard-boiled eggs. The sauce should coat generously without being runny; if it has thickened while resting, loosen it with a little hot water.
