How to Make It
Preheat the oven to 350°. On a floured surface, roll out the dough to a 13-inch round a scant 1/4 inch thick. Fit the dough into a 10-inch glass pie plate and trim the overhang to 3/4 inch. Fold the dough under itself and crimp decoratively. Refrigerate the pie shell for 10 minutes.
Line the pie shell with foil and fill with pie weights or dried beans. Bake in the center of the oven until nearly set, about 25 minutes. Remove the foil and weights and bake until the crust is pale golden, about 10 minutes longer. Let cool slightly.
In a medium bowl, whisk the egg yolks with 1/2 cup of the sugar, the cornstarch, cinnamon, cloves and salt until smooth. Whisk in the pumpkin puree then whisk in the cream. Using a handheld electric mixer, beat the egg whites at medium-high speed until soft peaks form. Gradually add the remaining 1/4 cup of sugar and beat until the whites are glossy, about 1 minute longer. Fold the beaten whites into the filling. Working near the oven, pour the filling into the crust. Bake the pie for about 45 minutes, until the custard is set and the top is cracked; cover the edge of the crust with strips of foil if it browns too quickly. Cool the pie on a wire rack completely before serving.
