Prepare the Pie Crust:

• In a large bowl, mix the flour, salt, and sugar.
• Add the chilled butter and mix until the mixture resembles coarse crumbs.
• Stir in ice water, one tablespoon at a time, until the dough comes together.
• Divide the dough in half, shape into discs, wrap in plastic, and refrigerate for at least 1 hour.

Make the Apple Filling:

• Preheat your oven to 425°F (220°C).
• Peel, core, and slice the apples into thin wedges.
• In a large bowl, toss the apple slices with sugar, flour, cinnamon, nutmeg, and lemon juice until evenly coated.

Assemble the Pie:

• Roll out one dough disc on a floured surface and place it in a 9-inch pie dish.
• Fill the crust with the apple mixture, dot with butter.
• Roll out the second dough disc and place it over the filling. Seal and cut slits in the top crust for ventilation.

Bake the Pie:

• Bake in the preheated oven for 15 minutes.
• Reduce the temperature to 350°F (175°C) and bake for an additional 35 to 45 minutes, or until the apples are tender and the crust is golden brown.

Cool and Serve:

• Allow the pie to cool for at least 2 hours before slicing to set the filling.
