Useful to know
King Arthur’s traditional angel food cake relies on whipped egg whites, sugar and a little flour. The pan is left ungreased, and the cake cools upside down after baking. [1]
The source links this cooling method to preserving the structure. Do not replace the pan instructions with a habit of greasing every tin. The vessel must allow the specified inversion and safe cooling. Distinguish this egg-white cake from chiffon, which also contains fat and yolks.
