I found a recipe in Better Homes and Garden cookbook:
1 1/2 cups sugar 1/3 cup cold water 2 egg whites 1/4 teaspoon cream of tarter or 2 teaspoons light-colored corn syrup 1 teaspoon vanilla
1. In the top of a double boiler combine sugar, cold water, egg whites, and cream of tarter or corn syrup. Beat with an electric mixer on low speed for 30 seconds
2. Place over boiling water (upper pan should not touch water). Cook, beating constantly with the electric mixer on high speed, about 7 minute or till frosting forms stiff peaks. Remove from the heat; add vanilla. Beat 2 to 3 minutes more or till it reaches spreading consistency. This frosts the tops and sides of two 8- or 9-inch cake layers or one 10-inch tube cake.
