Also known as Bumbu Kacang, this is a rich, savory peanut sauce made of fried earthnuts, aromatic garlic, and bird’s eye chilies, all balanced by the deep sweetness of Kecap Manis.
Ingredients:
- 1 cup raw peanuts (fried until golden) or roasted peanuts.
- 2 cloves of garlic
- 1–3 Thai bird’s eye chilies (depending on your spice preference).
- 2 tbsp Kecap Manis
- 1 tsp palm sugar or brown sugar
- 1 tsp tamarind paste or lime juice
- A pinch of salt
- ½ tsp of Terasi (Indonesian shrimp paste)
- ½ to 1 cup warm water
Methods:
- Fry/Roast: Sauté the peanuts, garlic, and chilies in a little oil until the garlic is fragrant and the peanuts are toasted.
- Grind: Traditionally, this is done with a mortar and pestle, but you can pulse everything in a blender.
- Simmer: Transfer the paste to a small pan, add the water, kecap manis, sugar, and tamarind. Simmer on low heat until the oil begins to separate slightly, and the sauce thickens.
