Start by cubing your butter and shortening and placing it into the refrigerator to stay very cold while you prepare the other ingredients
Measure out 1/2 cup of water and place it into the freezer to get as cold as possible while you prepare the other ingredients
Weigh out 315 grams of all purpose flour in a large bowl and whisk in 1 teaspoon of salt
Add the chilled, cubed butter and shortening and cut it into the flour mixture using a pastry cutter or two stiff forks
Once the butter and shortening are in pea sized pieces and evenly distributed throughout the flour mixture, begin drizzling very cold water into the bowl a tablespoon or two at a time mixing to incorporated between each drizzle
Once the dough begins to come together, transfer it onto a lightly floured surface
Knead quickly to bring it together
Divide the dough into two equal portions
Flatten each portion into a disk (photos above) and wrap tightly with plastic wrap
Chill the wrapped dough in the refrigerator until you are ready to use (up to 5 days)
Unwrap one portion of dough and transfer it onto a lightly floured surface
Gently roll out your dough into a round large enough to cover your pie dish
Transfer the dough over your pie dish and gently press it into the base and up along the sides
Use a sharp knife to trim away excess
Transfer the prepared pie dough into the refrigerator to chill while the filling is prepared
Preheat your oven to 375 degrees
