These are all herbs and spices I have in my cupboard permanently, but feel free to substitute them with the real deal, this is just a quick and easy way to make satay sauce. The sweet soy sauce is a crucial ingredient though! Normal soy sauce will not make this taste the same. Luckily most supermarkets sell this in their foreign speciality section these days. You might need to add a bit more water or a bit more peanut butter to thicken or thin it to your liking, it depends a little on which brand peanut butter you use as well, same with the sugar.
