Apple Turnovers

4 apples, peeled, cored and diced

2 T. butter

1/2 c. brown sugar, packed

1 t. cinnamon

2 t. cornstarch

1 sheet frozen puff pastry, thawed

1 egg 

Melt butter in a skillet or sauce pan over med high heat.  Add the apples, brown sugar, cinnamon and cornstarch.  Cook and stir until apples are tender and caramelized and the sauce is thickened, about 5 minutes. Set aside to cool slightly.

Roll the pastry into a 15"square.  Cut into quarters so that you have 4 even squares.  

Whisk the egg with 1 T. water.  Brush each square with the egg wash.  Add 1/4 of the apple filling onto each square, fold into a triangle and seal the edges by pressing with a fork.  Brush the top of each turnover with the egg wash.

Bake in a preheated 400* oven for 20-25 minutes, until golden brown.
