Empanadas Tucumanas (Chopped Beef Empanadas)
Instead of browned mince, this Tucumán-style filling starts with a whole piece of matambre, a thin beef flank cut, simmered about two hours and then diced by knife, and its broth is split between filling and dough so both carry the beef flavor. The filling is spread out and chilled before shaping, as beef fat in the pastry softens quickly against anything warm.
