Mom's Apple Pie

I could eat this pie every day. It is incredible. If you've never cooked your apple pie in a brown paper bag, you've got to give it a try. It cooks perfectly every time.

Mom's Apple Pie
5 cups granny smith apples, sliced thin
1/2 cup sugar
1/2 tsp. nutmeg
1/2 tsp. cinnamon
1/2 tsp. salt
2 Tbsp. flour
2 Tbsp. lemon juice

Mix. Put in uncooked pie shell. Mix until crumbly:
3/4 cup flour
3/4 cup sugar
3/4 cup butter

Sprinkle over apples. Put pie pan in a large paper bag. Staple closed. Put on cookie sheet (to catch any drips) on a low rack. Bake at 350 degrees for exactly 1 hour and 45 minutes.
