PUMPKIN BUTTERSCOTCH PIE

Steps:

• For crust:
• Mix flour, sugar, and salt in processor. Add butter; using on/off turns, process until very coarse meal forms. Add 3 tablespoons ice water; using on/off turns, process until moist clumps form, adding more water by teaspoonfuls if too dry. Gather dough into ball; flatten into disk. Wrap and chill 1 hour.
• Roll out dough to 12-to 13-inch round. Transfer to 9-inch-diameter glass pie dish. Fold edges under and crimp decoratively. Chill dough until firm, about 1 hour. DO AHEAD: Can be made 1 day ahead. Cover and keep chilled.
• Preheat oven to 350°F. Line crust with sheet of foil. Fill with dried beans or pie weights. Bake 20 minutes. Remove foil with beans. Bake until just beginning to turn golden brown, piercing with fork if bubbles form, about 15 minutes longer. Cool completely.
• For filling:
• Combine 1/2 cup brown sugar, butter, and salt in medium saucepan; bring to boil over medium heat, stirring to dissolve sugar. Boil until deep brown, about 5 minutes. Remove from heat. Add Scotch, then cream (mixture will bubble vigorously) and whisk until smooth. Return to medium heat and stir until most caramel bits dissolve. Strain butterscotch mixture into small bowl. Cool to room temperature, stirring occasionally.
• Whisk remaining 1/4 cup brown sugar and pumpkin in large bowl. Whisk in eggs, then spices. Add reserved butterscotch mixture; whisk to blend. DO AHEAD: Can be made 1 day ahead. Cover and chill. Rewhisk before using.
• Preheat oven to 350°F. Pour filling into crust. Bake until just set, about 50 minutes. Cool to room temperature, about 3 hours. DO AHEAD: Can be made 8 hours ahead. Store at room temperature.
• For whipped cream:
• Using electric mixer, beat cream, sugar, and Scotch in medium bowl until peaks form. DO AHEAD: Can be made 4 hours ahead. Cover and chill. Rewhisk if necessary before serving.
• Cut pie into wedges. Serve with dollop of whipped cream.
