Pie Crust:
3 C All-purpose flour
1/4 C sugar
1/2 tsp table salt
3/4 C unsalted butter (cold & cubed)
1/2 C shortening
3/4-1 C ice cold water
1 tsp distilled white vinegar
Stir together flour, sugar and salt. Using a pastry cutter cut into the butter and shortening until it is peas sized.
In a cup combine the water and the vinegar then while stirring gently slowly add the water to the flour/butter mixture, adding only enough to hold the dough together. Wrap in plastic and chill for at least an hour (at this point you can freeze it and thaw in the fridge before rolling).
Roll out on a lightly floured surface being careful to handle the dough as little as possible to avoid over working it.
Pie Filling:
1/2 C unsalted butter
3 T All-purpose flour
1/2 C white sugar
1/2 C packed brown sugar
1/4 C water
8 Granny Smith apples
Place the bottom crust in your pan. Fill with apples, mound slightly. Cover with a lattice work of crust.
Melt butter in a sauce pan. Stir in flour to form a paste, add white sugar, brown sugar and water; bring to a boil . Reduce temperature and simmer for 5 minutes.
Gently pour the sugar and butter mixture over the crust and into the apples, pour slowly so it doesn't run off.
Bake for 15 minutes at 425 degrees F. Reduce the temperature to 350 degrees F, and continue baking for 35-45 minutes.
