Directions:
Put into one tumbler of flour one teaspoonful of cream of tartar, then sift it five times. Sift also one glass and a half of white powdered sugar. Beat to a stiff froth the whites of eleven eggs; stir the sugar into the eggs by degrees, very lightly and carefully, adding three teaspoonfuls of vanilla extract. After this add the flour, stirring quickly and lightly. Pour it into a clean, bright tin cake-dish, which should not be buttered or lined. Bake at once in a moderate oven about forty minutes, testing it with a broom splint. When done let it remain in the cake-tin, turning it upside down, with the sides resting on the tops of two saucers so that a current of air will pass under and over it.

This is the best recipe found after trying several. A perfection cake.
