Mix all ingredients well and put in a kettle to cook over low heat. Stir continuously until mixture thickens.
When thick, pour into a buttered pan about 2 inches deep. Let stand until cold. Invert pan and remove batter. Cut into diamond-shaped pieces and pile them back into the buttered pan.
Dot with butter and brown in a moderate oven (preheated to 350 degrees).
Serve in beef consommé, chicken broth, or other clear soups.
