Melt an ounce of butter in a Saucepan; mix smoothly with it one ounce of flour, a pinch of salt and cayenne and a quarter of a pint of milk; simmer the mixture gently over the fire, stirring it all the time, till it is as thick as melted butter, stir into it about three ounces of finely-grated parmesan, or any good cheese. Turn it into a basin and mix with it the yolks of two well-beaten eggs. Whisk three whites to a solid froth, and just before the souffle is baked put them into it, and pour the mixture into a small round tin. It should be only half filled, as the fondu will rise very high. Pin a napkin around the dish in which it is baked, and serve the moment it is baked. It would be well to have a metal cover strongly heated. Time twenty minutes. Sufficient for six persons.
