Kecap manis

Sweet soy sauce is a sweetened aromatic soy sauce, originating in Indonesia, which has a darker color, a viscous syrupy consistency, and a molasses-like flavor due to the generous addition of palm sugar or jaggery. Kecap manis is widely used with satay. It is similar to, though finer in flavor than, Chinese Tianmian sauce (tianmianjiang). It is by far the most commonly employed type of soy sauce in Indonesian cuisine and accounts for an estimated 90 percent of the nation's total soy sauce production.
