Seven Minute Frosting
2 egg whites, unbeaten
1½ cups sugar
5 tablespoons water
1½ teaspoons light corn syrup
1 teaspoon vanilla
Combine egg whites, sugar, water, and corn syrup in top of double boiler, beating with rotary egg beater until thoroughly mixed. Place over rapidly boiling water, beat constantly with rotary egg beater, and cook 7 minutes, or until frosting will stand in peaks. Remove from boiling water; add vanilla and beat until thick enough to spread. Makes enough frosting to cover tops and sides of two 9-inch layers, or top and sides of 8 × 8 × 2-inch cake (generously).
