Grated pie, probably an invention of my late grandmother, is pie made of pastry dough that is frozen and then grated, instead of defrosted and rolled out. I hesitate to compare this dough to pâte brisée, since the recipe is completely unorthodox, but pastry crust is what it tastes like when baked. This is an admittedly odd recipe and technique, but it’s a longtime family favorite because it's easy and convenient. You can make the crust and freeze it, and when you have a hankering for some pie all you need is a pie pan, filling and a grater. I have yet to make this dough myself, but this recipe has always worked for my mom. I used one of her ready-made batches to bake a very good apple-pumpkin pie a couple of weeks ago.
For the crust: Beat together 3 eggs and 1 cup of sugar. Melt 2 sticks of butter; cool, add to eggs and sugar. Add 2 tablespoons of sour cream; mix well. Sift 2 cups of flour and 1/2 tsp. baking soda. Add the flour to the wet ingredients gradually, and knead until you form dough. Add more flour if the dough is too wet--about 1/2 cup should do it. Divide the dough into two rounds, wrap, and freeze.
For the filling: I sautéed four sliced, peeled and cored apples in some butter. When the apples were soft, I added a splash of Calvados, some sugar--1/3 cup, maybe?--a little nutmeg, ground cloves, cinnamon and ground ginger, and about a cup of canned pumpkin (not pumpkin pie filling).
For the pie: You’ll need ½ crust recipe (one frozen round of dough). Butter a 9-inch pie pan. Grate the frozen dough until it covers the bottom of pan. Use your fingers to press on the dough so that it covers the entire pan and its sides. I used about ¾ of the dough round for this. Add the filling, spreading it evenly over the dough. Grate the remaining dough over the top. Use your fingers or a knife to fold the dough on the sides onto the filling. Bake at 350 for 40-50 minutes, until the crust on top is nicely golden. Let cool.
