How to Make It
Combine sugar, egg whites (at room temperature), syrup, water, cream of tartar, and salt in top of a large double boiler; beat at low speed of electric mixer 30 seconds or just until blended.
Place over rapidly boiling water; beat constantly at high speed of electric mixer 7 minutes or until stiff peaks form. Remove from heat, and add vanilla; beat 1 minute or until frosting is thick enough to spread. Spread on cooled cake.
