Ingredients
1-1/2 cups all-purpose flour1-1/2 cups ground hazelnuts1 cup sugar, divided3/4 cup cold butter, cubed2 cups fresh blackberries2 cups fresh blueberries2 cups fresh strawberries, sliced3 tablespoons cornstarch
Preparation
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.
Place berries in a large bowl; sprinkle with cornstarch and remaining sugar. Stir until well blended. Spoon into crust. Sprinkle with reserved crumb mixture.
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.
