This recipe puts the blueberries grown in our area to good use. It's a great summertime dessert.—Frances Colley, Coos Bay, Oregon

Ingredients

  • 6 large eggs, separated
  • 1-1/2 cups sugar
  • 3/4 cup orange juice
  • 1-1/2 cups all-purpose flour
  • 1-1/2 teaspoons baking powder
  • 1/4 teaspoon cream of tartar
  • BLUEBERRY TOPPING:
  • 1/2 cup sugar
  • 2 teaspoons cornstarch
  • 1 tablespoon grated orange zest
  • 1/2 cup orange juice
  • 2 cups fresh or frozen blueberries
  • SOUR CREAM TOPPING:
  • 2 cups sour cream
  • 1 tablespoon confectioners' sugar
  • 1 teaspoon vanilla extract
  • grated orange zest, optional

Directions

  1. Let eggs stand at room temperature for 30 minutes. Sift flour and baking powder; set aside.
  2. Place oven rack in lowest position. Preheat oven to 325°. In a large bowl, beat yolks until slightly thickened. Gradually add sugar, beating until thick and lemon-colored. Blend in orange juice. Add dry ingredients to yolk mixture until well blended
  3. Add cream of tartar to egg whites; with clean beaters, beat on high until stiff but not dry. Fold a fourth of the egg whites into batter, then fold in remaining whites.
  4. Gently spoon into an ungreased 10-in. tube pan; smooth the top. Bake 50-55 minutes or cake springs back when lightly touched. Immediately invert the pan; cool completely.
  5. For blueberry topping, in a large saucepan, combine sugar, cornstarch and orange zest. Stir in orange juice until smooth. Bring to a boil; cook and stir for 2 minutes or until thickened. Remove from the heat. Stir in blueberries.
  6. For sour cream topping, in a large bowl, combine sour cream, confectioners' sugar and vanilla.
  7. Run a knife around side and center tube of pan. Remove cake to a serving plate; cut into slices. Serve with warm blueberry topping and the sour cream topping. Garnish with orange zest if desired.
