Blueberry Dream Pie

Directions

1. On a floured surface, roll each dough disk to fit a 9-in. deep-dish cast-iron or other cast-iron skillet. Line skillet with bottom crust. Trim crust to 1/2 in. beyond edge of skillet; flute edges. Line unpricked crust with a double thickness of heavy-duty foil. Bake at 450° for 8 minutes. Remove foil; bake 5 minutes longer. Cool on a wire rack. Reduce heat to 375°.
2. In a small bowl, beat the cream cheese, confectioners' sugar and lemon juice until light and fluffy. Beat in egg yolk until blended. Spread into crust.
3. In a large saucepan, combine 1/2 cup sugar, flour and cornstarch; stir in water until smooth. Stir in 2 cups berries. Bring to a boil; cook and stir until thickened, 1-2 minutes. Cool slightly. Gently stir in the lemon juice, mint and remaining 4 cups berries. Pour over cheese filling.
4. Cut decorative cutouts from remaining crust; arrange over filling, leaving center uncovered. Brush crust with egg white; sprinkle with remaining 1 tablespoon sugar.
5. Bake at 375° until crust is golden brown and filling is bubbly, 35-40 minutes. If necessary, cover edges with foil during the last 15 minutes to prevent overbrowning. Cool on a wire rack. Refrigerate leftovers.
