Preheat the oven to 400 degrees. Place a large sheet pan in the oven.
Cut each apple into 4 quarters. Cut each quarter in half. Make sure to peel and core every apple. I prefer to peel each slice as I go. I recommend using an apple slicer to make it faster!*Tip: Not necessary but I like a mixture of apple chunks and slices. So some of my apples I will cut the slices into 3 chunks. It makes for a fun texture! In a large mixing bowl, combine your apples, lemon juice, orange juice, sugar, flour, and cinnamon. Combine well.
Grab our pie dish and roll out half the pie dough. *Tip: It's really important that your pie dough and butter are kept in the refrigerator the entire time until they are ready to be used. The colder they are the better for baking. Fill the pie with half of your apple mixture. Using your hands, be sure to accommodate little chunks and pieces to have as little holes/gapes as possible.
Fill with the rest of your mixture. The apples will shrink during cooking so don't be scared of the height.
Top with the second pie crust. Crimp together the two pie crusts with a fork.
In a small bowl, crack one egg and mix with 1 tablespoon of water. Whisk until well combined. Using a brush, brush the entire top crust with your egg wash.
Sprinkle 1 tbs of white sugar around the pie crust.
Using a sharp knife, delicately cut a few slits around the pie about 4-6.
Place the pie on the hot sheet pan that is already in the oven. Bake for 1 hour or until the pie crust is golden and you can see some of the mixture bubbling.
