3. For topping, cream together flour, sugar, and margarine. Spoon mixture on top of pie.
4. Bake for 10 minutes. Reduce to 350 degrees F and bake for another 30 minutes. Enjoy!
I like to bake this in a square casserole dish instead of a pie dish. If you want to use a premade crust, it works equally as well as the homemade one. However, the homemade crust is so easy to make, you may as well. I prefer to use granny smith apples for their tart, crisp taste. They're very good baking apples. For this recipe, I halve the sugar, using 1/4 brown sugar and 1/4 white for the filling and the topping. You may also add a smidge of cinnamon to the topping if you like.
