Place the sliced and peeled apples in a large bowl. Mix together flour, sugar and cinnamon. Add to your apples, stirring. Coat well (I use my hands!)
Set aside to prepare your crust. I use pre-made Pillsbury crust and work it into the pie plate. Homemade is great too.
Pour Apple mixture in crust. Cover with the following topping:
½ C Butter (at room temp)
½ C Flour
½ C Sugar
Mix topping until crumbly. You can use a fork, but I use my hands. Mixture will be lumpy and soft. Crumble it on top of your apples using your fingers. Last, you will want to smear some butter along the outside crust-edges, as this is the 1st to darken while baking.
Place pie in a brown paper-bag. Fold the ends under. Place bag onto cookie sheet. Using the lowest rack of your oven, bake at 400 for one hour.
Sack will not burn. Don’t forget the vanilla bean ice cream
