Satay sauce, bumbu kacang, or sambal kacang, is an Indonesian sauce made from roasted or fried peanuts, coconut milk, soy sauce, tamarind, galangal, garlic, and spices. The sauce is generally cooked for a few minutes to allow the ingredients to meld. It's often served with chicken satay. Thai peanut sauce doesn't exist in Thailand and is an American invention. In Thai food, you'll often find ground peanuts on dishes, accompanied by a squeeze of lime, a sour sauce, a spicy sauce, and sugar. But these ingredients are not combined into a peanut sauce. Our peanut sauce recipe uses Thai flavors to create a Thai-inspired peanut sauce.
