Argentine food writers widely treat Tucumán as the empanada's true home base, and the province even markets an official 'Camino de la Empanada' driving route past its most famous roadside stands.
A juicy, fried or baked pastry filled with hand-knife-chopped (never ground) beef, onion, and cumin, baked in wood-fired clay ovens at roadside stands across Tucumán. The knife-cut meat keeps the filling looser and juicier than machine-ground versions elsewhere.
