Equipment
Double boiler or heat proof mixing bowl that will fit over a medium saucepan
Mixer
Ingredients
5egg whitesroom. temperature
¾cupgranulated sugar
¼teaspooncream of tartar
⅛teaspoon salt
1 teaspoon pure vanilla extract
Instructions
In the pot of a double boiler, bring some water to a boil and then lower the heat to a simmer. In the top portion of the double boiler, mix together the egg whites, sugar, salt, and cream of tartar.You can also use a heat proof mixing bowl and place it over, but not into, a medium pot of simmering water.
Heat the egg white mixture while whisking constantly until warm and sugar has completely dissolved. The egg will be warm and the mixture smooth when rubbed between your fingers. This should take about 3-4 minutes.
Transfer mixture to your mixing bowl (if not already using it to heat the egg), and using the whisk attachment, and starting on low speed beat the mixture gradually increasing to high speed until stiff, glossy peaks form. This will take about 7-9 minutes.
Add the vanilla and mix until combined. Use immediately.
Notes
Makes enough frosting for a 9 X 13-inch cake, 12 cupcakes, or the outsides of a double layer 8-inch or 9-inch cake. Due to the consistency, I personally don't think it's a sufficient filling for a cake, and just recommend using it to frost the top and sides.
