06Shape into a rectangle and pound with a rolling pin until it is about the size of a sheet of notebook paper, approximately 8 1/2 by 11 inches.07Use the bench scraper to fold the dough into thirds, like a letter. Pound with the rolling pin until the piece of dough is again the size of a sheet of notebook paper and rotate 90 degrees. Repeat the pounding, folding, and rotating 2 more times for a total of 4 turns of the dough.08Pound with rolling pin and fold the shorter sides of the rectangle in towards the center, from top to bottom, and then fold in half, like a book. Wrap in parchment paper and refrigerate for 1 hour.09For the egg wash: Combine the beaten egg and water in a small dish and set aside.10To build the pie: Divide the warm filling into 4 (16-ounce) ramekins and place on a half sheet pan lined with parchment paper.11Remove the puff pastry from the refrigerator. Divide in half. Return one half to the refrigerator. Sprinkle lightly with flour and roll to 1/4-inch thick and, using your ramekins as a guide, cut 2 circles that are 1/2 inch wider than the rim, using a sharp knife or pizza cutter. Repeat with the other half of the dough. Refrigerate excess dough for another use.12Brush each dough round with egg wash and place egg washed-side down onto the top of each filled ramekin. Brush the top of the pastry with egg wash. Bake for 15 minutes. Decrease the heat to 400 degrees F and bake until the crust is puffed and golden brown and the filling is bubbly, another 15 to 20 minutes. Cool on a rack for 10 minutes before serving.
