This deeply flavoured oxtail dish starts with the oxtail intensely marinated in variety of Jamaican spices then braised down for the perfect taste. Oxtail is the tail of a cow. In olden days, it came from the tail of an ox, but now it comes from the tail of a cow of either sex. The tail is skinned and cut into sections; each section has a tailbone with some marrow in the center, and a bony portion of meat surrounding the tail.
