Preheat oven to 425 degrees

Peel, core, and slice apples.

Place one of the pie crusts in a sprayed pie pan. Add apples, creating a mound.

Prepare lattice design for top pie crust. Set aside.

Melt butter in a saucepan over medium heat. Stir in flour to form a paste. Add water, white sugar and brown sugar, and bring to a boil. Reduce temperature and let simmer. Add cinnamon, nutmeg, and vanilla. Stir to combine and remove from heat and let cool down a bit.

Pour ½ of the sugar and butter liquid over the apples and add the lattice crust on top. Slowly pour remaining sugar mixture over crust, letting it seep into the openings.

Bake 15 minutes in the preheated oven. Reduce the temperature to 350 degrees F and continue baking for 35 to 45 minutes, until apples are soft. (Note: place a cookie sheet on the rack beneath the pie in case there is any runoff.)

Move pie to bottom oven rack if the top crust is getting too done.
