2 pounds Granny Smith apples
2 pounds Braeburn apples
1 teaspoon ground cinnamon
3/4 cup granulated sugar
1/2 cup butter
1 cup firmly packed light brown sugar
1 (14.1-oz.) package refrigerated pie crusts
1 egg white
2 tablespoons granulated sugar
Butter-pecan ice cream
Preheat oven to 350º. Peel apples, and cut into 1/2-inch-thick wedges. Toss apples with cinnamon and 3/4 cup granulated sugar.
Melt butter in a 10-inch cast-iron skillet over medium heat; add brown sugar, and cook, stirring constantly, 1 to 2 minutes or until sugar is dissolved. Remove from heat, and place 1 pie crust in skillet over brown sugar mixture. Spoon apple mixture over pie crust, and top with remaining pie crust. Whisk egg white until foamy. Brush top of pie crust with egg white; sprinkle with 2 Tbsp. granulated sugar. Cut 4 or 5 slits in top for steam to escape.
Bake at 350º for 1 hour to 1 hour and 10 minutes or until golden brown and bubbly, shielding with aluminum foil during last 10 minutes to prevent excessive browning, if necessary. Cool on a wire rack 30 minutes before serving. Serve with butter-pecan ice cream.
