Instructions: Prepare the crust: Using a pastry cutter or your hands, work the butter into the flour mixture until it resembles coarse crumbs with some larger pea-sized pieces.
Prepare the filling: Preheat your oven to 425°F (220°C).In a large bowl, combine the sliced apples, sugar, flour, cinnamon, nutmeg, and lemon juice. Toss until the apples are evenly coated.
Roll out the crust: On a lightly floured surface, roll out one disc of the chilled dough into a circle about 12 inches in diameter.
Assemble the pie: Roll out the second disc of dough into a similar-sized circle and place it over the filling. Trim any excess dough and crimp the edges to seal. Cut slits in the top crust to allow steam to escape.
Bake the pie: Place the pie on a baking sheet (to catch any drips) and bake in the preheated oven for 45-55 minutes, or until the crust is golden brown and the filling is bubbling.
Cool and serve: Allow the pie to cool on a wire rack for at least 2 hours before slicing and serving. Serve warm or at room temperature, optionally with a scoop of vanilla ice cream or a dollop of whipped cream.
