Peanut sauce or satay sauce is widely used in the cuisines of Thailand, Malaysia, Indonesia, china and many more places. The main ingredient for peanut sauce is crushed roasted peanuts but can substitute with smooth or crunchy peanut butter. In Thai version, lemon grass, galangal or ginger, fish sauce or soya sauce, lemon juice or tamarind paste, coconut cream, red chilli are added as per the taste. Peanut sauce can be used as a dipping sauce, with salad, noodle, marinate and in spring roll as a stuffing. This time I have prepared peanut sauce with peanut butter (smooth). It is up to you how spicy and sweet you want.
