Freeze uncooked balls of dough or freeze dough in pie tins. FILLING: Place a ball of chilled dough on a piece of lightly floured wax paper and pound with a rolling pin to flatten and soften. Roll the dough into an 11-inch circle, lift it with the wax paper and invert onto a 9-inch glass pie dish. Press firmly into the dish and gently remove and discard wax paper. Place in refrigerator to chill. Preheat oven to 400F. Arrange apples in the pie crust. In a bowl, beat together eggs, half-and-half, sugar, vanilla and mace. Pour the mixture over the apples. Place the pie in the oven and bake until the mixture is set, about 30 minutes. The dough recipe makes about 3 10-inch pies.
