Heat the oven to 450 degrees F.
Combine the flour and salt in a food processor (this can also be done by hand). Pulse to blend.
Add 5 Tbsp. butter. Pulse until combined.
Add other 5 Tbsp. of butter. Pulse until combined and there are pea-size crumbles.
Add the water and process until a ball of dough forms.
Split the dough in half.
Roll one of half of the dough on a floured surface and place it in a 9" pie pan.
In a large bowl combine the remaining ingredients for the filling.
Pour the filling into the prepared pie crust.
Roll the remaining crust on a floured surface.
Cover the filling with the pie crust and seal edges.
Cut slits in the top to allow steam to escape.
Place the pie pan on a sheet pan (in case of spills).
Bake for 10 minutes in preheated oven.
Reduce heat to 350 degrees F and bake for another 40 - 45 minutes.
Allow pie to cool completely before serving. This allows the filling to fully set.
Serve plain or with ice cream or whipped cream.
