Caramel Apple Pie (The best pie I have ever tasted.)

Pie crust for double crust pie
8 peeled and sliced apples
1/2 cup butter
3 Tbsp all purpose flour
1/4 cup water
1/2 cup white sugar
1/2 cup packed brown sugar
1 tsp cinnamon
1/4 tsp nutmeg
1 Tbsp cornstarch
1 tsp vanilla

Notes/Story: Preheat oven to 350. Melt butter in saucepan. Stir in flour to make a paste. Add water, white sugar, brown sugar, cinnamon, nutmeg, cornstarch, and vanilla and bring to a boil. Reduce temperature and let simmer. Pour 2/3 of caramel sauce over apples and mix well. Reserve 1/3 of sauce for top of pie.

Place the bottom crust in your pan. Fill with apples. Place top crust over apples and drizzle the rest of the caramel sauce on top. Bake in preheated oven for 1 hr.
