Apple Pie by Grandma Ople

"I found this recipe on allrecipes.com. This is someone else's grandma's recipe, not mine, but I'm sure my grandma also made a mean apple pie. This is the original, but please read my notes at the bottom."

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

DIRECTIONS:
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. Fill with apples, mounded slightly. Cover with a lattice work of crust. Gently pour the 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.

NOTES:

-As suggested by a review you can add 1 teaspoon cinnamon and a dash of nutmeg to the syrup. You can also omit a tablespoon of water from the 1/4 cup and add one tablespoon vanilla.

-Eight apples were way to many to fit into my pie, so I think Seven would be better

-the butter and flour didn't turn into a paste for me even though I added an extra two tablespoons

-my pie overflowed and dripped at the bottom of the oven. It also took an extra ten minutes of baking time to get the apples soft enough.
