I found this recipe in a woman's magazine back in the seventies and have used it ever since. It has never failed ME, at any rate. No matter how much this dough is handled it is always flaky and tender even if scraps need to be re-rolled. Be sure to use exact measures, levelling off with a knife. Dough can be left in the refrigerator for up to 3 days. It remains soft and can be taken out and rolled at once, or it can be frozen until ready to use (thaw until soft enough to roll). For a filled pie, bake at temperature indicated in recipe you are using. For unfilled pie, bake at 450 degrees Fahrenheit as directed below. Note that it is suggested you bake a filled pie versus a pie shell on different racks of the oven. The recipe makes five 9-inch pie shells or one shell plus two 2-crust pies. Preparation time includes minimum chilling time of 1/2 hour. Cooking time is for unfilled pie crust only.
