On a lightly floured surface, roll out the remaining dough to a thickness of ⅛ inch. Cut into twelve strips, each 1 inch wide. Arrange them on a baking sheet lined with parchment paper and chill in the refrigerator for 10 minutes, or until the pie filling has cooled completely.
Pour the cooled filling into the prepared pie dish. Place 6 strips of the dough in the same direction, evenly spaced on top of the filled pie shell. Fold back ever other strip then place a piece of dough on top of the pieces that you did not fold up. Place them right up to the folded dough. Unfold the dough strips.
Next fold back the strips of dough that you didn't fold back the first time. Repeat the process of placing a piece of dough over the pieces laying on the filling. Unfold the dough and continue with one more strip.
Rotate the pie and repeat the process. Trim any excess dough and seal the edges by lifting each strip, brushing with water, and firmly pressing it onto the dough in the pie shell.
Brush with egg wash and sprinkle sugar on top. Place a tin foil pie collar around the edges of the pie crust and bake for 40 minutes. Remove the foil collar and continue baking for another 20 to 25 minutes, or until the filling is bubbly. If the crust starts to brown excessively, replace the foil pie collar. Allow the pie to cool completely before slicing. Enjoy!
