Often referred to as "Indonesian soy sauce," Kecap Manis is a syrupy, dark brown sauce sweetened with palm sugar and seasoned with things like garlic and star anise.

Used as a condiment and for marinating dishes like satay (and ribs), Kecap Manis should be kept in a cool, dry place. Though it's generally a little sweeter than soy sauce, you can use the two interchangeably.
