Basically, the debate exists on whether to use butter, shortening, lard, or some combination for the flakiest, best-tasting pie crust. I like a combination of butter and shortening for pie crusts. The shortening helps it to be super flaky, tender, and sturdy, while the butter gives it a delicious buttery flavor. The combination results in a delicious, flaky, yet perfectly sturdy crust that works for even heavier pie fillings.
