Spiced beef empanadas

This is one of my new favorites.

I got this recipe from Real Simple magazine a few months ago.  I've already made it several times. It is easy (although a little time consuming) and so delicious.  

Spiced Beef Empanadas:

1 Tbsp. Olive Oil
1 small onion, chopped
1/2 pound ground beef
1/3 cup golden raisins
2 Tbsp. ketchup
1/4 tsp. ground cinnamon
s/p
2 store-bought refrigerated rolled piecrusts (I get GF ones from BitterSweet Bakery)
1 large egg, beaten
1/2 cup sour cream
1/4 tsp. lime zest

Heat oven to 375 degrees.  Heat the oil in a large skillet over medium head. Add the onion and cook, stirring occasionally, until soft, 5 to 6 minutes.  Add the beef and cook, breaking it up with a spoon until no longer pink, 3 to 4 minutes. Stir in the raisins, ketchup, cinnamon, salt and pepper.

Using a 2 1/2 inch round cookie cutter (or biscut cutter) to cut out circles from the piecrusts. Divide the beef mixture among the circles, brush the edges with water, fold in half, and press with a fork to seal.  Transfer to a baking sheet and brush with the egg. Bake until golden, 20 to 25 minutes.

Put the sour cream in a small bowl and sprinkle with the lime zest. Serve with the empanadas.
