A cooked peanut sauce of ground roasted peanuts, aromatics, shrimp paste and coconut cream, as made for gado-gado; pecel and Malaysian satay sauces are close relatives with different formulas.

Indonesian gado-gado with cooked peanut sauce, vegetables, noodles, tofu and egg.

A family of peanut sauces

Peanut sauce is not one recipe. An Indonesian government culinary book describes Java's bumbu kacang as the sauce served with sate, gado-gado, karedok, ketoprak and pecel, with a sambal kacang for other foods. The indexed text of the page names fried peanuts, palm sugar, garlic, shallot, ginger, tamarind, lemon, lemongrass and water. Every version grinds peanuts into a base and seasons it with chilli and aromatics. How sweet, how sour, how thick, whether it is cooked and whether it contains coconut or shrimp paste changes from dish to dish and cook to cook.

The gado-gado sauce

The formula on this page is Sukiman Kadir's, shown at the 2010 Smithsonian Folklife Festival for gado-gado, a platter of steamed vegetables, yellow noodles, egg and fried bean curd. The peanuts, garlic, shallots and chillies are blended with a little water. Lemongrass, ginger, galangal, salam leaves, lime leaves, shrimp paste and lemon juice are sauteed in oil until fragrant, which draws their aroma into the fat before the peanut paste goes in. Coconut cream and water loosen and enrich it, brown sugar and sweet soy sauce sweeten and colour it, and a low simmer thickens it. The finished sauce is poured over the arranged dish and topped with fried shallots. It is one festival demonstration, not a canonical gado-gado.

Pecel and satay: related sauces, different formulas

Pecel is boiled vegetables dressed with a diluted peanut sambal. A Yogyakarta seller's recipe makes the paste dry and uncooked in the sauce sense: 500 g peanuts, fried or dry-roasted and ground; 100 g shaved palm sugar and three lime leaves; a tablespoon of tamarind; and a paste of fried red curly and bird's eye chillies, garlic, kencur, roasted shrimp paste and salt. All are mixed, and a portion is thinned with warm water at serving. A cultural database entry describes pecel in the same terms but lists no supporting documents or heritage designation.

A Malaysian satay sauce is a cooked relative. Bee Yinn Low's eight-serving recipe blends dry-roasted peanuts with a paste of soaked dried chillies, garlic, shallots, lemongrass and galangal, adds tamarind, palm sugar, coriander, sweet soy sauce, oil and water, and simmers five to ten minutes until thick. It is useful as comparison, not as an Indonesian master formula.

Fermented ingredients, fresh risk

Some formulations use terasi or shrimp paste as a seasoning. That does not make the finished sauce fermented, since the paste is an ingredient and the sauce is ground, mixed and often cooked at serving scale. The sources give no common shelf life, and their home storage notes are not tested controls. A Pekanbaru journal abstract found E. coli in all five unbranded market samples of peanut sambal and Salmonella in three. Only the abstract was available, so the methods are unreviewed, and a small local study cannot speak for all peanut sauces or supply a household storage limit. It is a reason to serve the sauce freshly cooked and keep leftovers cold.

Method

Risks and precautions · Elevated risk
Peanut, shrimp and soy allergens

The sauce is built on ground peanuts and contains shrimp paste and sweet soy sauce.

Hazard source
Microbial contamination of market sauces

A Pekanbaru journal abstract reports E. coli in all five unbranded market samples of peanut sambal and Salmonella in three. The full paper was not reviewed, and this small local study does not measure all peanut sauces or establish causes.

Hazard source

Bring the sauce to a boil and simmer it as the recipe directs, serve it freshly made, and keep any left over cold. No source gives a validated shelf life for a home batch.

Control source

The recipe is one festival demonstration; it is not a standard formula for Indonesian peanut sauce.

Some source formulations use shrimp paste as a seasoning. That does not make the sauce fermented, but it does add a crustacean allergen.

  1. In a food processor, blend the ground peanuts, garlic, five of the shallots, ground red chillies, salt and the 1/4 cup of water.
  2. Heat the vegetable oil in a pot. Saute the lemongrass, ginger, galangal, salam leaves, lime leaves, shrimp paste and lemon juice until fragrant.
  3. Add the peanut mixture and cook for a few minutes.
  4. Add the coconut cream and 1 cup of water and mix until smooth.
  5. Add the brown sugar and more salt if wanted, then the sweet soy sauce.
  6. Bring to a boil, then simmer over low heat, stirring from time to time, until thick.
  7. Pour the sauce over the arranged dish and scatter it with fried shallots.
