Both satay and peanut sauce are similar. However, satay sauce typically contains a blend of spices like turmeric, garlic, and chili, as well as peanuts and coconut milk. On the other hand, peanut sauce is made with ground peanuts, a mild chili pepper, garlic, and other spices. The variations in the ingredients and the spiciness of the sauce are what make them distinct. While both sauces are delicious and versatile, satay sauce is more likely to be found served with grilled proteins, while peanut sauce is commonly served with stir fry dishes like noodles and vegetables, or as a dressing for salads.
