Margo Moon, your wish is my command.
2 cups unbleached white flour
1/4 tsp. salt
1 tsp. sugar
1/2 lb. cold unsalted butter (keep it as cold as you can)
1/4 cup vegetable shortening
1/4 cup ice water
Mix the flour, salt, and sugar in a bowl. Chop the butter into small cubes and cut half of it into the flour mixture until the mixture resembles coarse meal. Add the shortening and the remaining butter and cut them in, leaving 1/4 inch pieces. (This is what will make the dough flaky.) Sprinkle in the ice water, tossing lightly with a fork to moisten it evently, until the dough holds together.
Divide the dough in half and press into 2 balls. Wrap each in plastic wrap and let them rest for 4 hours (or longer) in the fridge. Lightly flour a work surface and roll the circles out. They will go into two 9-inch pie pans. Keep the crusts refrigerated until you're ready to fill and bake them.
