Heat oven to 400°F. Make pie crusts as directed on box for Two-Crust Pie using 9-inch glass pie plate.
In large bowl, place apples, 3/4 cup sugar, the cornstarch and orange peel; toss to coat apples. Spoon 1/2 of apple mixture into crust-lined pie plate. Sprinkle evenly with raspberries. Top with remaining apple mixture. Dot with butter. Top with second crust; seal edges and flute.
Lightly brush crust with water; sprinkle with 1 teaspoon sugar. Cut slits in several places in top crust. Cover crust edge with strips of foil to prevent excessive browning.
Place pie on middle oven rack; place sheet of foil on rack below pie in case of spillover. Bake 45 to 55 minutes or until deep golden brown. Cool at least 1 hour before serving.
