Preheat your oven to 375 degrees F and lightly grease a 9" deep dish pie plate with cooking spray. Meanwhile, in a large bowl, stir together the apples, sugars, spices, and salt. Let sit for 30 minutes, then drain the apple mixture, discarding the liquid. Toss the apples with the cornstarch.

On a flat, clean work surface, stack two pie crusts together and roll them out with a rolling pin until you get a 12"-13" circle. Gently drape the pie crust over the pie plate and pat in the bottom and up the sides of the pan. Fill with the apple mixture.

With the remaining pie crusts, stack again and roll out to about a 10" circle. Using a pizza cutter, cut into 1" strips. In a striped pattern, lay the strips a couple centimeters apart on the top of the apple surface. Brush the pie strips lightly with the egg wash. Going in a horizontal pattern, stagger the other pie strips and brush with egg wash. Sprinkle liberally with the coarse sugar.

Tent the edges of the pie with foil or pie shields, and bake for approximately 15 minutes. Reduce your oven temperature to 350 degrees F and bake for 50-60 minutes more until the top is light golden and the filling is bubbly. Cool for at least 1 hour before serving.

To make your cinnamon whipped cream: with a handheld electric mixer or stand mixer, whip the heavy cream, confectioners' sugar and cinnamon together on high speed for about 5 minutes or until soft peaks form.
