Paper Bag Apple Pie

Pare and core about 8 cooking apples. Cut into quarters and cut these in half (not 1/8). Place in a large bowl and set aside. Combine and mix well: 1/2 C. sugar, 2 T. flour, 1/2 t. cinnamon (the original recipe calls for nutmeg, but my family prefers cinnamon). Sprinkle over apple chunks and toss slightly. Spoon into prepared shell. Sprinkle over top: 2 T. lemon juice. Combine in bowl: 1/2 C. sugar, 1/2 C. flour. Mix well and add 1/2 cup butter or margarine. Cut in butter with a pastry blender or two knives until mixture is coarse, like cornmeal. Sprinkle this mixture evenly over top of pie. Slide pie into a large, heavy supermarket paper bag. Fold open end twice and fasten with paper clips. Place on a baking sheet. Bake at 425 for 1 hour. Remove from oven, split bag open and cool pie on wire rack. DO NOT open bag while baking! This is a great pie and one that friends always request from me. Enjoy!
