1. In the top of a double boiler melt the butter over simmering water. Add the flour with constant stirring until it is well blended in and the mixture is bubbly. Remove from heat and gradually whisk in the chicken stock and the cream. Return to the heat and quickly bring up to a boil, stirring constantly. Cook for 1-2 minutes while still stirring. Remove from heat and stir about 3 Tbs of the sauce into the 2 slightly beaten egg yolks, adding the sauce little by little. Add the egg yolk mixture to the remainder of the sauce off heat, stirring all the while. Cook over simmering water for 3-5 minutes, stirring slowly all the while. Remove from heat, cool slightly, and add the cheeses all at once and blend in until all of the cheeses have melted. Serve at once as suggested. ---------------------------------------------------------------------------
