As described over the phone to me by my friend Faye Stein
Author: Jane Maynard
Ingredients
4 egg whites
1 cup sugar
15-20 ounces butter (american style, the regular stuff you get at the store), room temperature
1 teaspoon vanilla
Instructions
Combine the egg whites and the sugar in a KitchenAid bowl. Place over a pan of simmering water. Whisk thoroughly until the temperature reaches 165 degrees (which actually happened faster than I was expecting). The mixture will be shiny and the sugar dissolved. Remove from heat, place on mixer.
With the whisk attachment, whisk at high speed until it’s a meringue, stiff peaks forming. Stop whisking, let mixture cool until bowl is cool enough to touch and the mixture is room temperature.
Whisk at medium high speed, breaking off pieces of butter and adding, mixing after each addition. The mixture will stay quite soupy and you’ll think there’s no way that this is going to turn into frosting”¦and you’ll get ready to grab your phone to call me and find out what you’re doing wrong even though I told you it would work (that’s what I did with Faye)”¦but you just keep whisking and whisking, and then all of the suden it’s right. It suddenly turns into creamy frosting wonderfulness. (I added about 15 ounces of butter total the first time I made it, 12 ounces the second time I made it). At the point that it looks like actual frosting, add your vanilla and any food coloring and whisk again for a few minutes.
Leftover frosting can be frozen for future use. Once you’ve refrigerated or frozen the frosting, if you want to mix it in the mixer again you should use the paddle attachment, not the whisk attachment.
