Argentinian Beef Empanadas
Set racks in upper and lower thirds of oven, and preheat to 450 degrees F. Line 2 large baking sheets with parchment paper.Advertisement
Cook beef in a large, heavy skillet over medium-high heat, stirring and breaking up lumps, until no longer pink, 4 to 5 minutes. Transfer beef to a small bowl with a slotted spoon, and pour off grease from skillet. Melt butter in skillet and saute onions and green onion, stirring occasionally, until tender, about 5 minutes. Return beef to skillet and stir in hard-boiled eggs, olives, raisins, cumin, salt, and pepper. Transfer mixture to a shallow bowl and chill until cooled, 10 to 20 minutes.
Unfold 1 pastry sheet, keeping remaining chilled, onto a lightly floured surface, dust lightly with flour, and roll out into a 12-inch square. Cut 4 (5 1/2-inch) rounds from pastry. Brush a 1/2-inch border around edges of 1 round with water, using a small brush or fingertip. Spoon about 3 tablespoons of filling onto half of round. Fold other half over filling and press edges together firmly. Crimp edges with a fork and transfer to one of prepared baking sheets. Repeat with 3 remaining rounds. Form 12 more empanadas in same manner with remaining pastry and filling, arranging them about 1 1/2 inches apart on baking sheets.
Brush tops of empanadas with beaten egg. Bake, switching position of sheets halfway through, until golden brown, about 15 minutes.
