Prepare a sponge when scalded milk is lukewarm by adding two cups flour and dissolved yeast cake; beat thoroughly; cover and set to rise. When light, add well beaten eggs, Cottolene worked to a creamy consistency, sugar, salt and flour enough to knead (about six and one-half cups). Knead until smooth and elastic. Roll out to one-fourth inch thickness, spread generously with soft butter, sprinkle thickly with sugar and cinnamon, mixed and sifted. Roll like jelly roll; cut off slices one-half inch thick; set them close together, cut side down, in a greased dripping pan. Brush between rolls with melted Cottolene, cover and set to rise. When light, bake thirty minutes in a moderate oven, remove from oven and brush over with white of egg diluted with two tablespoons cold milk. Return to oven to brown; repeat, to make them glossy.
