Protein Frosting

Place all the ingredients in a metal bowl that fits inside a saucepot then set the filled metal bowl aside.

Bring a saucepot filled 1/3 of the way with water to a soft boil, place the bowl into the saucepot and let the water simmer under the bowl as you mix with an electric hand mixer. As the egg cooks it will thicken. It will take about 7 minutes of mixing. As the mixture gets hot and is thickened, remove the bowl from the saucepan and finish mixing it on the counter. The frosting is ready when the mixture forms stiff peaks when you lift the beaters. Use immediately to frost angel food cake or angel food cupcakes.
