My favorite flaky, delicious buttermilk pie crust (made with a food processor). This is seriously the easiest pie dough you will ever make or work with!
*If you measured your flour by weight, you will need closer to 1/2 cup of buttermilk for a full double crust, but if you measure your flour by volume, you will almost certainly technically have more than 2 1/2 cups of flour (scooping flour into measuring cups tends to compress it), so you will probably end up needing closer to 2/3 cup. Use just enough buttermilk for your dough to hold together. Using too much can result in a tough, crunchy finished product.
