Triple-Berry Crumb Pie

Directions

1. Preheat oven to 375°. In a large bowl, combine flour, hazelnuts and 1/2 cup sugar; cut in butter until crumbly. Set aside 1-1/2 cups crumb mixture for topping. Press remaining mixture onto the bottom and up the sides of an ungreased 9-in. deep-dish pie plate.
2. Place berries in a large bowl; sprinkle with cornstarch and remaining sugar. Stir until well blended. Spoon into crust. Sprinkle with reserved crumb mixture.
3. Bake 55-60 minutes or until crust is golden brown and filling is bubbly (cover edges with foil during the last 15 minutes to prevent overbrowning if necessary). Cool on a wire rack.
