If you like a lot of apples use more apples. I used six cups.
Also if you don't want to use crust for topping the pie, there is a recipe for Streusel...I haven't made it this way before but I'm going to try it this year.Streusel Topping: In a medium bowl combine 3/4 cup flour, 1/2 teaspoon cinnamon,1/4 teaspoon ground cloves, 1/2 c brown sugar, 3/4 c oats, and 1 tea lemon peel. Mix thoroughly, then cut in 1/2 cup butter or margarine until mixture is crumbly. pour over pie before baking and pat to seal ..make sure there are no openings where filling can seep through. bake, halfway till pies done..put tin foil on top and over edges of crust.
