The Tucumán region of Argentina is famous for these handmade empanadas filled with finely chopped beef and onions. Sometimes raisins, olives, and hardboiled eggs are added, although raisins and olives are not traditional. The secret of these empanadas Tucumánas is to cut the beef into very small pieces. The filling tastes best when you make it 1 day ahead
