Start by washing and coring your apples. Instead of cutting the cores out, I like to slice the sides of the apple away from the core.
Slice the apple into slices about ¼ inch thick. As you cut, submerge the slices in water to keep them from browning. Use a bowl large enough to mix the slices when done.
When done slicing, drain the water well, then add all of the filling ingredients except the butter. Mix until well combined. The apple slices should be uniformly coated in apple pie filling goo.
Spray your pie pan with cooking spray, then lay out one of the pie crusts inside it.
Fill the pie dish with your apple pie filling. Dice the butter and spread the cubes around the pie.
Lay the second pie crust over the pie, and pinch it sealed with the bottom crust. If you have significant extra overhand, tear it off.
Cut four small ovals out of the center of the pie crust. This is both ornamental and lets the pie breath while cooking.
Mix the egg and water together with a fork. Wash the top crust in this egg mix. This is easiest if you have a brush.
Sprinkle sugar over the top crust.
Bake at 425F for 20 minutes, you’ll see the crust start to brown.
Reduce the temperature to 375F and bake for another 30 minutes. You might need to bake a little longer, the crust should be golden and the pie should be visibly bubbling from the holes.
Let the pie completely cool before serving, at least 2 hours. Enjoy :)
