Combine flour and salt in a large chilled bowl.
Cut cold butter into the flour using a pastry cutter until the mixture resembles coarse crumbs.
Add ice-cold water one tablespoon at a time, mixing gently until the dough clumps together.
Shape dough into two disks, wrap in plastic, and refrigerate for 60 minutes.
Peel and slice apples into half-inch wedges.
Toss apple slices with sugar, cinnamon, and lemon juice in a large bowl.
Roll out the first dough disk on a floured surface and fit into a pie dish.
Fill the crust with the apple mixture.
Roll out the second disk and cover the pie, crimping the edges to seal.
Bake at 375°F for 60 minutes or until golden brown and bubbling.
