Deep-Dish Apple-Blackberry Pie

Ingredients

• 1 1/2 tablespoons lemon juice
• 1 teaspoon vanilla extract
• 1 1/2 pounds tart apples (about 6 apples)
• 2/3 cup plus 1 tablespoon granulated sugar, divided
• 1/4 cup cornstarch
• 2 cups fresh or frozen blackberries (not thawed)
• 1 recipe Walnut Pastry Dough (recipe follows)

Directions

Preheat oven to 350 degrees F. Coat a 9-inch deep-dish pie pan with nonstick spray.

Combine lemon juice and vanilla in a large bowl. Peel, core and cut apples into 3/4-inch chunks, tossing them in the lemon juice mixture as you work.

Mix 2/3 cup sugar and cornstarch and toss with apples. Add blackberries.

Place 2 overlapping sheets of plastic wrap on a work surface. Set the larger disk of dough in the center and cover with 2 more sheets of plastic wrap. Roll the Walnut Pastry Dough into a 13-inch circle. Remove top sheets and invert dough into the prepared pan, letting excess dough hang over the edges. Gently press the dough into bottom and sides of pan. Pull off plastic wrap. With a rubber spatula, scrape the apple-blackberry filling into pie shell.

Roll out smaller disk of dough as above, making an 11-inch circle. Remove top sheets of plastic and invert dough over filling. Pull off plastic wrap. Press together edges of pastry to seal. With the tip of a sharp knife, cut 3 or 4 short slashes to vent steam. Moisten a pastry brush with water and lightly brush top of pie. Sprinkle with the remaining 1 tablespoon sugar. Place the pie on a baking sheet with sides.

Bake until crust is golden and filling bubbles, 45 to 55 minutes. Cool on a wire rack for about 1 hour. Serve warm or at room temperature.
