Make a thick white sauce, using butter, flour, and milk, add yolks of eggs without first beating, and stir until well mixed; then add cheese. As soon as grated cheese melts, remove from fire and season with salt, pepper, and cayenne. Spread in a shallow pan and cool. Turn on a board, cut in small squares or strips, dip in crumbs, egg, and crumbs again, fry in deep fat, and drain on brown paper. Serve for a cheese course.
