Angel Food Cake
No butter, no oil, no yolks: this tall white ring cake rises entirely on whipped egg whites folded with cake flour and sugar. It likely appeared in late 19th-century America as a way to use whites left over from custard making. The top has a slight marshmallow chew over a cloud-light crumb. The pan goes upside down the moment it leaves the oven, because cooling right side up lets the delicate foam sink under its own weight. Fresh berries and whipped cream are the traditional companions.
