This interesting sauce is the Caribbean oil-based variation on the African sauce from Angola, which was transferred to the region by Portuguese immigrants working the cacao plantations in Trinidad and Guyana. Can be used in place of olive oil in almost any recipe. Pimento leaves are traditionally used in this recipe, but are hard to find. NOTE: This recipe requires minimum 2 weeks advance preparation. From "Too Many Chiles" by Dave DeWitt and Nancy & Jeff Gerlach.
