For Pie Crust:

1. In a medium bowl combine the flour and salt.
2. Add the cold butter. Using clean hands work it into the flour until it is a coarse texture with a few larger chunks.
3. Slowly drizzle the cold water in a little bit at a time, working it into the dough. When the dough begins to clump together stop adding water.
4. Form the dough into a disc shape and cover. Chill for at least 2 hours.
5. Spray a pie dish with non-stick spray. Set aside.
6. Place the dough on a clean and floured surface and begin to roll it out. The dough should be about ⅛ of an inch thick.
7. Pick the dough up by rolling it around your rolling pin and then unrolling it over the pie dish. Adjust the dough so that it lays flat against the pie dish. You can cut off or crimp the edges to your liking.
8. Place the crust in the fridge until ready to use.
9. Preheat the oven to 450 degrees (F)

For Pie Filling:

1. In a large bowl add the diced apples, brown sugar, cornstarch, cinnamon or apple pie spice, and lemon juice. Toss until the apples are fully coated. Allow to sit for five minutes.

For Crumble Topping:

1. In a small bowl, combine sugar, flour, butter, and cinnamon or apple pie spice. Use clean hands or a fork to mix together until the butter is broken up and the mixture has a coarse texture.

For Assembly:

1. Pour the pie filling into the cold crust and spread out evenly.
2. Pour the crumble over the top of the apples and spread out evenly. Place the pie in the preheated oven and bake for 10 minutes then turn the oven down to 350 degrees (F) and bake for another 45 minutes. Remove from the oven and allow to cool before serving.
