Combine egg whites, sugar, cream of tartar and water in the top of a double boiler over simmering water. Beat egg white mixture 1 minute. Increase heat on double boiler to medium high and beat mixture an additional 7 minutes on high speed. Remove frosting mixture from over water and add vanilla. Beat another 2 minutes on high speed.
