                    I got this recipe out of a TOH magazine years ago, I've never had any problems with it. But according to the person that submitted it J. Ference she never had a problem either! All cooking times are approximate. Ingredients: 
                    
                        
                                                1/3 cup butter or 1/3 cup margarine  |  
                                                1/3 cup all-purpose flour  |  
                                                2 cups milk  |  
                                                1 teaspoon dijon mustard  |  
                                                1/4 teaspoon salt  |  
                                                1 dash hot pepper sauce  |  
                                                1 1/2 cups swiss cheese, shredded  |  
                                                1 cup cheddar cheese, shredded  |  
                                                1/4 cup parmesan cheese, shredded  |  
                                                6 eggs, separated  |  
                                                1/2 teaspoon cream of tartar  |  
                                                
                     
                    Directions: 
                    
                        
                            
                                1. Melt butter in a medium saucepan. 2. Stir in flour; cook for 1 minute until bubbly. 3. Gradually add milk, mustard, salt and hot pepper sauce; cook and stir until thickened and bubbly. 4. Add cheeses; stir until melted. 5. Remove from the heat and set aside. 6. In a small mixing bowl, beat egg yolks until thick and lemon colored, about 3-4 minutes. 7. Add 1/3 cup cheese mixture and mix well. 8. Return all to the saucepan; return to the heat and cook for 1-2 minutes. 9. Cool completely, about 30-40 minutes. 10. In another mixing bowl, beat egg whites until soft peaks form. 11. Add cream of tartar; continue beating until stiff peaks form. 12. Fold into the cheese mixture. 13. Pour into ungreased 1 cup souffle dishes or custard cups. 14. Place in a shallow pan. 15. Pour warm water into larger pan to a depth of 1 inches Bake uncovered at 325 for 40-45 minutes or until tops are golden brown. 16. Serve immediately. 17. *NOTE* Souffles can be made ahead and frozen. Cover each dish or cup with foil and freeze. To bake, remove foil and place unthawed souffles in a shallow pan; add warm water to a depth of 1 inches Bake at 325 for 60-65 minutes or until tops are golden.                              |
