Seven Minute Frosting

This frosting goes so well on chocolate cake. I have it on an old hand written recipe card, but it is in the Mennonite Treasury too.

• 1 egg white
• 1/8 teaspoon cream of tarter
• 1/3 cup boiling water
• 1 scant cup white sugar
• pinch salt
• 1 teaspoon vanilla

1. Place sugar, salt, cream of tarter and boiling water in the top of a double boiler. 
2. Have the egg white ready in a small bowl to add.
3. Over the hot water bath begin beating the water sugar mixture and add egg white beating with an electric hand mixer.
4. Continue to beat for 5-7 minutes until mixture is very white and billowy and stands at a peak when you pull up on the beaters. You can also test it by slicing through the frosting with a knife. It should retain a clean cut.
5. Remove from heat and add in salt and vanilla.
6. Immediately frost completely cooled cake with warm frosting.
