To make lattice top, cut second crust into 1/2-inch-wide strips with pastry cutter. Place half of the strips across filling in pie plate. Weave remaining strips with first strips to form lattice. Trim ends of strips even with edge of bottom crust. Fold trimmed edge of bottom crust over ends of strips, forming a high stand-up rim. Seal and flute. Brush lattice strips with egg. Sprinkle remaining 1/3 of topping over pie. Place sheet of foil over pie to prevent excessive browning; bake 20 minutes. Remove foil; bake 15 to 20 minutes longer or until topping is golden brown. Cool at least 2 hours before serving.
