Angel Cake * 9 egg whites * 1 teaspoon cream of tartar * 1 cup sugar * 7/8 cup flour * 1/8 teaspoon salt * 1 teaspoon vanilla 1. Beat the whites of the eggs to a froth, add the cream of tartar and beat till the eggs are stiff but not dry, then gradually add the sugar (which has been sifted twice), beating after additions. 2. Sift the flour with the salt five times and fold it into the mixture. 3. Add the vanilla. 4. Bake in an ungreased angel cake tin in a very moderate oven (250-320 degrees F.) for forty-five minutes. 5. Be careful not to jar or disturb while baking. 6. Remove from the oven, turn the pan upside down on a wire netting or with a knife handle or some other small article inserted under the edge of the pan to permit steam to escape, and let it stand until the cake falls out. 7. Ice placed on the bottom of the tin will hasten the release of the cake.
