6-8 Granny Smith apples - peeled, cored and sliced (I also like macintosh)
Preheat oven to 425 degrees F (220 degrees C). Melt the butter in a saucepan. Stir in flour to form a paste. Add water, white sugar and brown sugar, and bring to a boil. Reduce temperature and let simmer.
Place the bottom crust in your pan. Mix apples with 2/3 of cinnamon sugar mixture. Pour apples into pie crust, piled high.
Cover with a lattice work of crust. I roll mine out into a rectangle and cut with a pizza roller, pretty simple! Gently pour the remaining sugar and butter liquid over the crust. Pour slowly so that it does not run off.
Bake 15 minutes in the preheated oven. Reduce the temperature to 350 degrees F (175 degrees C). Continue baking for 35 to 45 minutes, until apples are soft
*I pre-bake my crust at 425 for 8 minutes before I add my apples so that it doesn't get soggy, you could brush it with egg whites instead.
