Cranberry-Blueberry Pie

FOR THE PASTRY:
Place the flour, sugar, salt and butter in a food processor fitted with a metal blade. Process until the mixture resembles coarse meal.

Whisk together the egg yolk and ice water in a small measuring cup with a pouring spout. With the processor running, add the liquid through the feed tube. Process just until the dough begins to form a ball.

Turn the dough out onto a lightly floured surface, divide it in half and shape each half into a round flat disc. Wrap each in plastic wrap and refrigerate for at least one hour.

FOR THE FRUIT PIE FILLING:
Combine the blueberries, cranberries, orange zest, sugar, cinnamon and nutmeg in a large bowl and mix well. Dissolve the cornstarch in the orange juice in a large saucepan.

Add the berry mix and bring all to a boil over medium-high heat. Cook, stirring constantly until thickened, 5 to 8 minutes. Remove from heat and let cool completely.

TO ASSEMBLE AND BAKE PIE:
When ready to assemble the pie, preheat the oven to 375 degrees F. Roll half of the dough out into a 13-inch circle on a lightly floured surface. Transfer the dough to a 9-1/2-inch deep-dish glass pie plate. Trim the edges, leaving a 1/2-inch overhang; reserve the trimmings. Spoon the berry filling into the dough.

Roll the other half of the dough into another 13-inch circle. Transfer it to the pie pan to to cover the filling. Trim the edges and pinch together with the bottom crust to form a decorative crimped edge. Make several slashes in the top crust to allow steam to escape during baking. Brush the crust lightly all over with the heavy cream.

Gather the reserved dough trimmings into a ball and re-roll to 1/8-inch thickness. Cut out decorative shapes, arrange atop the crust and brush them with heavy cream. Sprinkle the top of the pie with granulated sugar.

Place the pie on a cookie sheet lined with foil and bake until the crust is golden brown and the berry juices are bubbling, 60 to 70 minutes.

Let the pie cool to room temperature. Accompany with vanilla ice cream, if desired.
