In a large bowl, toss the apple slices with the granulated sugar and 1/4 cup flour.
Using a 9 inch pie pan, roll out one pie crust. Be sure to press it down. Add the apples.
In a small bowl, mix the cinnamon, salt, brown sugar and 1/2 cup flour. Sprinkle on top of the apples. Squirt the lemon juice on top, and then dot the pie with butter.
Add the top crust. Turn the top crust under the bottom and flute the edge. Cut slits in the top for steam to escape. *
Bake for 30 to 40 minutes, or until crust is golden brown and inside is hot.
Notes
*As pictured, sometimes I like to cut the top pie crust into strips to create a lattice design on the top. Using a pizza cutter makes this task quite simple!
