Rhu-berry Pie Recipe

Roll out pastry to fit a 9-in. pie plate. Transfer pastry to pie plate. Trim pastry to 1/2 in. beyond edge of plate; flute edges. In a large heavy saucepan, combine sugar and cornstarch. Stir in apple juice until smooth. Cook and stir over medium heat until thickened. Add rhubarb; cook and stir gently 2-3 minutes or just until heated through. Stir in blueberries. Spoon mixture into pie shell. Place a foil-lined baking sheet on a rack below the pie to catch any spills. Bake at 375 ° for 45-50 minutes or until bubbly. Cool completely on a wire rack.
