Use canned, unseasoned pumpkin -- not pumpkin pie filling -- for this pie.
½ recipe Perfect Pie Pastry (see below)
2 cups pumpkin
1½ cups whipping cream
½ cup brown sugar
¼ cup maple syrup
½ teaspoon salt
1 teaspoon cinnamon
½ teaspoon ginger
¼ teaspoon allspice
Preheat oven to 425 F.Combine all filling ingredients and beat until well mixed. You may use an electric beater; whisking by hand will also work.
