1/2 cup egg whites (about 4 large whites yield 1/2 cup)
1/2 teaspoon cream of tartar
2/3 cup superfine sugar
Set the bowl in a skillet of gently simmering water and whisk until the whites are warm, not hot, to the touch (110┬░ to 115┬░F). Remove the bowl from the skillet and beat on high speed until the whites are stiff. Sift the powdered sugar and cocoa over the meringue and fold in with a rubber spatula. Shape and bake as directed in To Form and Bake Meringues and Dacquoise or recipe.
