Boiled White Icing
2 cups sugar
1 cup water
2 egg whites
1/8 tsp. salt
1/8 tsp. cream of tartar or a few drops of lemon juice
1 tsp. vanilla
Bring sugar and water to a boil in heavy saucepan. Cover and cook for 3 minutes, until the steam has washed down any crystals on the sides of the pan. Uncover and cook to 238 degrees on a candy thermometer. The syrup, when dropped from a spoon, will spin a very thin thread on the end of a thicker thread.
Then, whip egg whites and salt until frothy. Add the syrup in a thin stream, beating constantly. When these ingredients are all combined, add the cream or tartar OR lemon juice, then beat in the vanilla.
