Pre-heat your oven to 350F.
Using an electric blender, blend together the eggs, sour cream and milk for 30 seconds. Blend in the black pepper, dry mustard, nutmeg and Tabasco.
Brush the butter all over the inside of the soufflé dish. Layer the cheese in the soufflé dish, then pour the egg mixture gently over the top. Leaving 1-inch of space at the top to prevent spillage as you carry it to the oven.
Place the soufflé dish in the oven, then carefully pour the remaining egg mixture to fill to the tippy top of the dish.
Bake for 55 to 60 minutes—the soufflé will be golden brown, puffy like a balloon, and will have risen up to three inches above the ramekin.
Present immediately to guests, as this dish will begin to fall in about 45 seconds. (if the soufflé does not fall, then the second law of thermal dynamics, does not exist in your home—if this occurs, call NASA right away)
