In a bowl, whisk together flour and salt.

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

Gradually add ice water, mixing until the dough just comes together.

Form the dough into a disc, wrap in plastic wrap, and refrigerate for at least 30 minutes.

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

Preheat oven to 375°F (190°C).

On a lightly floured surface, roll out half of the dough into a circle and place it in a pie plate.

Pour the apple filling into the pie crust and dot with butter.

Roll out the remaining dough and place it over the filling. Crimp the edges to seal.

Cut slits in the top crust for venting.

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

Let cool before serving.
