Oxtail, though contrary to its name, is NOT the tail of an ox but rather of a cow. A package of Oxtail typically weighs one to two pounds and is cut into short lengths. The Oxtail is literally one-of-a-kind (as there is only one per cow). A treasure in many cultures (European, Asian, South American, West African, Caribbean), Oxtail dishes boast of rich flavors. Oxtail is a collagen-rich meat, which is normally slow-cooked as a stew or braised, though some modern recipes call for the use of a pressure cooker.
