Prepare as directed above except use a purchased 9-inch graham cracker crumb pie shell instead of tarts. Spoon filling into pie shell. Bake for 60 minutes or until filling is set (160 degrees F). Mound all the egg white mixture atop the cooled pie. Broil 5 to 6 inches from the heat for 1 to 2 minutes or until top is lightly browned. Let stand 10 minutes before serving.
