This pan works perfectly, better than any other pan I've tried (including non-stick) for angel food. The aluminum (not too thin, not too thick) has a subtely machined finish that the angel food climbs easily. The pan is nice and tall, and has "ears" to keep the pan off the counter during cooling (keeps the cake from collapsing, and keeps the cake-top crunchy).
If you've made angel food before, you know that it relies on sticking to the pan sides in order to rise. With non-stick pans (which this is not and you don't want) either the cake won't rise fully if the sides are too slick, or if the cake climbs correctly it has by definition stuck to the sides and you will ruin the pan's coating when you go to saw out the cake with your knife. With this bare aluminum pan, the cake climbs fully and there's nothing to damage - saw away. A brief soak and it comes clean easily. Perfect.
