4 tbsp. butter
4 tbsp. flour
1 1/2 c. milk
1 tsp. salt
6 eggs
1/2 lb. cheese

Make a sauce of the butter, flour, hot milk and seasonings. When thickened and smooth, remove from the heat and add the cheese broken into pieces. Stir until the cheese is melted, then add the beaten egg yolks and mix well. Cool the mixture, then fold in the stiffly beaten egg whites.

Pour into a 2 quart buttered baking dish and bake for 1 1/4 hours at 300 degrees.
