History & Origins
Cordoban Bullring Tradition
Originating in 16th-century Córdoba, Andalusia, Rabo de Toro was historically prepared after bullfights using the prize bull tail, braised slowly with local red wine and mountain aromatics into an unctuous delicacy.

Finishing, Garnishes & Chef’s Additions

Step-by-Step Instructions
PREPARATION & METHOD
Season oxtail segments generously with sea salt and black pepper; dust lightly with flour. Heat olive oil in a large Dutch oven over medium-high heat. Sear oxtail in batches for 4 to 5 minutes per side until deeply browned and crusted. Transfer to a platter.
In the rendered drippings, sauté diced onions, sliced leeks, and carrots over medium heat for 10 minutes until caramelized. Stir in garlic and pimentón de la Vera for 1 minute until deeply fragrant.
Pour in red wine, scraping up all browned fond. Return oxtail pieces and pour in beef broth with bay leaves. Bring to a simmer, cover with a tight lid, and transfer to a 300°F (150°C) oven for 3 to 3.5 hours until the meat is meltingly tender and slips off the bone.
Transfer oxtail to a warm serving platter. Strain or blend the braising vegetables with sauce until silky smooth. Skim excess oil, simmer sauce for 5 minutes until glossy and thick, then spoon over oxtail. Garnish with parsley and serve with fried potatoes.
Beverage Pairing

Culinary Science Insight
Collagen Breakdown into Gelatin Emulsion
Oxtail has among the highest connective collagen content of any beef cut. Extended low-temperature braising converts collagen into soluble gelatin, naturally thickening the wine braise into a glossy, velvety glaze without cornstarch.
