Butternut Squash, Sage, and Parmesan Pasties

Made these last night for dinner... we thought they were pretty tasty.  

Makes 2 large or 4 small pasties

Dough
1 1/3 cups all-purpose flour
Pinch of salt
2/3 cup chilled butter, cut into small pieces
6-8 tablespoons ice water

Filling
8 ounces butternut squash, peeled and cut into 1 cm cubes 
1 medium red onion, diced
1 clove garlic, crushed
1 tablespoon finely chopped sage
1 tablespoon finely chopped parsley
1/4 cup grated Parmesan cheese
2 tablespoons pine nuts, toasted

Sea salt
Freshly ground white pepper (or black)
1 egg, beaten

To make dough

Sift flour and salt into a large bowl. Using a pastry blender or knife, cut butter into flour until the mixture resembles fine breadcrumbs. Add 1 tablespoon of ice water at a time, gently tossing between additions, until the dough just holds together. Shape dough into a ball and wrap tightly in plastic wrap. Refrigerate at least 30 minutes before rolling out.

Before rolling out the dough, let it soften slightly so that it is malleable but still cold. On a lightly floured surface, roll it out to 1/8-inch thick. Cut out two circles using a plate or bowl as a guide.

To make pasties

Preheat oven to 375°F.

In a large bowl, combine butternut squash, onion, garlic, sage, parsley, Parmesan cheese, and pine nuts.

Spoon mixture over half of each dough round, leaving a 1-inch border around the edge. Sprinkle well with salt and pepper.

Moisten the edges of the dough with beaten egg. With cool hands, fold the pastry over and crimp the edges. (Use any crimping technique you like, just make sure it is well sealed. For the traditional Cornish method, see this YouTube video.) Cut a small slit in the top of each pasty. Brush all over with beaten egg.

Bake until golden and cooked through, about 40 minutes. Serve hot or warm.
