In a deep bowl, mix together the flour and salt with the butter and shortening. You can use your finger or pastry cutter or two butter knives.
You want to mix it into pea-sized lumps.
Add 1 tablespoon of ice water at a time and then toss it with your hands. Add a tablespoon at a time and toss, until it holds together but not too wet, around 4 tablespoon. Shape into a ball.
Divide the dough into 2. Sprinkle some flour onto your surface and around your rolling pin. Measure the dough to the size of the pie plate and add 2 inches border around the edges. Roll out the crust to that measurement.
Once you have the size, gently fold in half and put it onto your pie plate. Push gently so the crust lays on the side of the plate.
Add filling and top crust.
Apple Filling
Preheat oven to 425 degrees fahrenheit.
Mix salt, cinnamon, sugar and flour in a bowl. This is the cinnamon mixture.
Make a base layer of apple slices into the pie plate. Sprinkle half of the cinnamon mixture on top. Add the rest of the apple slices and then sprinkle the rest of the cinnamon mixture.
Put little pats of butter around the top of the apples. Cover with top crust. Crimp the edges and cut the excess crust.
Brush the top of the crust with the beaten egg. Make slits on the top of the crust for the pie to vent. Put the pie plate on a baking sheet.
Bake at 425 degrees fahrenheit for 15 – 20 minutes to make the crust a golden color.
Turn down your oven to 375 degrees fahrenheit and bake more for another 35 to 40 minutes. To see if its baked or not, poke through the slits to see if the apples are soft.
