Preheat oven to 425 degrees. Line a baking sheet with parchment paper; set aside. In a large bowl, combine sugar, cornstarch, salt, ginger, cinnamon, cloves, pumpkin puree, and 3 eggs. Beat well. Add evaporated milk, and combine. Set aside.
Between two pieces of plastic wrap, roll pate brisee into a 12-inch circle. Fit pastry into a 9-inch glass pie plate; trim dough evenly along edge, leaving about a 1/2-inch overhang. Pinch to form a decorative edge. If the dough begins to soften, chill for 15 minutes.
Make the glaze: Beat the remaining egg, and combine with heavy cream. Brush glaze very lightly on edges of pie shell. Fill pie shell with pumpkin mixture. Transfer to prepared baking sheet.
Bake for 10 minutes. Reduce heat to 350 degrees and continue baking for 30 minutes more. Cool on a wire rack.
In the bowl of a food processor, combine flour, salt, and sugar. Add butter, and process until the mixture resembles coarse meal, 8 to 10 seconds.
With machine running, add ice water in a slow, steady stream through feed tube. Pulse until dough holds together without being wet or sticky; be careful not to process more than 30 seconds. To test, squeeze a small amount together: If it is crumbly, add more ice water, 1 tablespoon at a time.
Divide dough into two equal balls. Flatten each ball into a disc and wrap in plastic. Transfer to the refrigerator and chill at least 1 hour. Dough may be stored, frozen, up to 1 month.
Yield: Makes 1 double-crust or 2 single-crust 9- to 10-inch pies
