Grandma Ople's Apple Pie Recipe

Ingredients
1 recipe pastry for a 9 inch double crust pie
1/2 cup unsalted butter
3 tablespoons all-purpose flour
1/2 cup white sugar
1/2 cup packed brown sugar
1/4 cup water
8 Granny Smith apples - peeled, cored and sliced

Directions
1.  Preheat oven to 425 degrees.
2. Melt butter in a sauce pan.
3. Stir in flour to form a paste.
4. Add white sugar, brown sugar and water; bring to a boil.
5. Reduce temperature, and simmer 5 minutes.
6. Meanwhile, place the bottom crust in your pan.
7. Fill with apples, mounded slightly.
8. Cover with a lattice work crust.
9. Gently pour the sugar and butter liquid over the crust. Pour slowly so that it does not run off.
10. Bake 15 minutes at 425 degrees F (220 degrees C).
11. Reduce the temperature to 350 degrees F (175 degrees C), and continue baking for 35 to 45 minutes.

NOTE: If adding cinnamon, add to the apples, not the sauce.
