In a large bowl, whisk together the flour and salt.

Cut in the cold butter using a pastry blender or your fingers until the mixture resembles coarse crumbs.

Gradually add the ice water, mixing until the dough just comes together. Form into a disc, wrap in plastic, and chill for at least 30 minutes.

In a large bowl, combine the apples, sugar, flour, cinnamon, and nutmeg.

Preheat oven to 375°F (190°C).

Roll out the bottom crust and place it in a pie dish. Add the apple filling and dot with butter.

Roll out the top crust and place it over the filling. Cut slits for venting.

Bake for 45-50 minutes, or until the crust is golden brown and the filling is bubbly.
