Here's the one I use. I think it's less about the ingredient choices than it is about getting comfortable making one. =P It took me forever and tons of practice to feel like I finally got it "right".
Crust to fit a 9” pie plate
1 cup + 2 Tbsp flour
1/2 teaspoon salt
1/3 cup butter
3-4 tablespoons milk
Combine the flour and salt. Using a pastry cutter, cut the butter into the flour mixture until there are pea-sized (or smaller) pieces of butter. Gradually pour the milk in, one tablespoon at a time while stirring the mixture. With your hands, mix the dough gently in the bowl. Place dough on heavily floured countertop, put flour over entire rolling pin surface and roll it out, gently until it’s about ¼ inch thick and large enough for your pie pan.
