A beautiful and useful dish for any day of the week, cheese souffle can be counted on to fill an emergency easily and with style. For variety, try making a souffle with Swiss cheese, with a combination of cottage cheese and Roquefort, or put a surprise ingredient (crab meat, sliced tomatoes, or hearts of artichoke) in the bottom of the dish. The recipe given is for a 6-cup souffle mold and serves three amply. If it is to be the main dish for four or five people, make 1 and ½ times the recipe (6 egg yolks, 7 or 8 whites) and use an 8-cup mold. For 6 servings it is best to double the recipe and use two 6-cup molds. Egg whites beat up better if they are at room temperature.
Set a rack in the middle of the oven and preheat the oven to 400 degrees F. Butter a straight-sided souffle dish well, and shake a little grated cheese around it.
Melt the butter, remove from the heat and stir in the flour and a bit of the milk. Return to low heat and gradually add the rest of the milk, the seasonings and the cheese and stir well. You will have a thick sauce.
Separate the eggs, stirring the yolks one by one into the sauce and dropping the whites (adding an extra one) into a clean, dry mixing bowl. Beat the whites until they stand in stiff peaks.
Stir a large spoonful (or the white that clings to the beater) into the sauce, then very quickly and lightly fold in the rest of the egg white. Spoon the mixture into the prepared souffle dish and place on the rack in the center of the oven. Immediately reduce the oven heat to 375 degrees F. In 25-30 minutes, the souffle will be well puffed but still creamy in the center. Allow it to cook for 5 minutes longer and take it to the table where you have already assembled the other elements of the meal and the guests.
