Angel Food Cake

I'm always looking for angel food cake recipes and have tried many. I may stop looking now as this is so good and so simple. Unlike many angel food cakes, this one is soft but not gummy when chewed. It slices very nicely and tastes very good just on its own. I like that the measurement for the egg white is a volume measure as well as the number of eggs. I frequently have containers full of egg whites and measuring out a cup and a half is so much nicer than guessing or weighing and approximating what 12 egg whites would be. I made this exactly as written and couldn't have more pleased with the results (lemon juice is another thing I always have lots of hanging about).
