Oxtail soup is made with beef tails. The use of the word "ox" in this context is a legacy of nomenclature; no specialized stock of beef animals are used. It is believed by some that oxtail soup was invented in Spitalfields in London in the seventeenth century by French Huguenot and Flemish immigrants, from the tails of animals. Different versions of oxtail soup exist: Korean, Chinese, a fried/barbecued oxtail combined with soup variation which is a popular dish in Indonesia where it is called as sop buntut. An ethnic dish of the American South which traces its lineage back to the pre-revolutionary war era, and a thick, rich, gravy-like soup popular in the United Kingdom since the 18th century. Creole oxtail soup is made from a tomato base with oxtails, potatoes, green beans, corn, mirepoix, garlic, and herbs and spices.
