I love putting new twists on old favorites. In my version of pumpkin pie, a crunchy hazelnut topping complements a creamy pumpkin filling in a tender, flaky crust. —Marie Rizzio, Interlochen, Michigan

Ingredients

2 cups all-purpose flour
2 tablespoons confectioners' sugar
1/2 teaspoon salt
3/4 cup cold butter, cubed
5 to 6 tablespoons ice water
