Take one of the pie crusts and unfold into a 9" pie dish
Brush the pie crust with egg white and allow to dry (this prevents the pie crust from getting soggy)
Peel, core and slice the apples. Put apple slices into a resealable bag along with the cinnamon, sugar and flour. Shake the bag well to coat all the apple slices evenly.
Empty the apples into the pie dish and spread out.
Take the last pie crust and slice into thin lines. Weave between each other on top of the pie. Then brush egg white over the top.
Cover top of pie loosely with a sheet of aluminum foil and place into the oven. Bake for 10 minutes. Then remove the foil.
Bake for another 35-45 minutes.
Remove from oven and allow to cool for 15 minutes before serving.
Notes
Using a Ziplok bag will make coating the apple slices much easier (and less dishes)Instead of weaving the top pie crust you can place the whole crust on top, but make sure to make 4 slits for the steam to escape.You can even ditch the top pie crust all together and make a crumble type of topping using flour, butter and sugar.
