1. Grab all of your crust ingredients and put them in a food processor. Blend until the butter is completely combined.
2. Form your dough into a disk and wrap it with plastic wrap. Refrigerate for at least 1-2 hours.
3. When your two hours is up, preheat your oven to 375°F.
4. Roll out about 3/4 of your dough onto a lightly floured surface and press into your pie dish.
5. Put a piece of parchment paper in the center of the dough, then place pie weights on top and bake for 15 minutes.
6. While this is baking, whisk sugar, zest, flour, egg whites and salt together in a large bowl. Add in your fruit and gently stir. Set aside.
7. When your crust is finished, pour your pie filling into the crust. Roll out your remaining dough and make the top crust. We went for a lattice look, but feel free to make it your own.
8. Mix together your egg wash ingredients and brush this liberally over the top of your pie crust.
9. Bake uncovered for 20-25 minutes.
10. Take out and cover the whole thing with foil.
11. Bake again for 15-20 minutes. Enjoy!

Recipe Notes: The dough can be made ahead and kept in the fridge or freezer.
