Quick answer

To make peanut sauce, whisk half a cup of peanut butter with half a cup of warm coconut milk, two tablespoons of soy sauce, a tablespoon each of lime juice and brown sugar, a grated garlic clove, and chili to taste. Thin with warm water to the job: thick for dipping, pourable for noodles.

What it is

What is peanut sauce?

Peanut sauce in Southeast Asia is a family of sauces, Indonesian satay\u2019s deep bumbu kacang, Thai restaurant versions rounded with coconut milk, Vietnamese roll dips loosened with hoisin, and the home pantry version borrows the balance logic that unites them: fat from the peanut, salt from soy or fish sauce, sour from lime, sweet from palm or brown sugar, heat from chili.

That five-way balance is the entire skill. Whisk the base, taste, and ask which corner is missing, salt, sour, sweet, or heat, and add only that. A sauce that tastes flat is usually short on sour, one that tastes muddy is short on salt.

2 tbsp

Method

How do you make peanut sauce?

  1. Whisk the peanut butter and warm coconut milk until fully smooth, it tightens then loosens, keep going.
  2. Whisk in soy, lime, sugar, garlic, chili, and ginger.
  3. Thin with warm water a spoonful at a time to the texture the job needs.
  4. Taste and rebalance: salt, sour, sweet, heat, one addition at a time.
  5. Serve at room temperature. Keeps five days refrigerated, re-loosen with warm water.
The four-corner taste test Before serving, taste for the four corners in order: salty enough? sour enough? sweet enough? hot enough? Fix exactly one at a time and stop when none is missing.

FAQ

Common questions.

Can I use regular peanut butter for peanut sauce?

Yes. Sweetened supermarket peanut butter works, just cut the added sugar in half. Natural-style whisks smoother and lets you control the balance completely.

How do I thin peanut sauce?

Warm water, a spoonful at a time, whisking between additions. Coconut milk thins it richer, lime juice thins it brighter, choose by what the sauce is missing.

Is this authentic Thai peanut sauce?

It is a pantry version in the Thai-restaurant style, coconut-rounded and balanced on the classic salt-sour-sweet-heat square. Indonesian satay sauce, its deeper cousin, starts from fried whole peanuts and shrimp paste.
