Yes! To make this cake a show-stopper, all you really have to commit to is to sift the dry ingredients 4 times. I hate sifting dry ingredients even once, but it's essential here. An angel food cake is so simple and has so few ingredients, and its light and fluffy texture is the whole point here. Sifting the flour mixture removes any clumps, and aerates it so that it distributes almost effortlessly into the whipped egg whites.
