Dust a clean work surface with flour and roll the pastry into a large rectangle about 1/16 to 1/8 inch thick. Cut the rectangle into 4 smaller rectangles (or circles, if you prefer turnovers of a more traditional "pasty" shape). You want them all to be roughly the same size. Brush the edges with a bit of beaten egg.☞ TESTER TIP: In a large bowl, mix the leftovers together, breaking up any pieces that may be a bit too chunky.
