Preheat the oven to 375 degrees.
In a stand mixer with a paddle attachment, combine flour, salt and sugar.
Add shortening and mix until just combined.
Add cold water and milk 1 tablespoon at a time. Mix until dough comes together.
Gather dough into a ball and shape it into a flattened round on a floured surface.
Roll pie crust into a circle 2 inches larger than the upside down pie plate.
Carefully transfer dough to pie plate and trim dough to a 1-inch overhang. Fold the extra piece under and pinch to seal it. Decorate edges as desired.
Using a fork, poke a couple of holes in the bottom of the crust.
Line the bottom of the crust with parchment and fill it with pie weights.
Bake the crust for 20 minutes.
Remove pie weights and parchment.
Bake for another 10-15 minutes, or until the bottom is golden.
