How do i make a steak diane sauce?
1) Finely chop a small onion and some closed cup or button mushrooms 2) heat some butter in a pan and add the onions and mushrooms and cook until soft 3) add some whiskey or brandy and heat (take care as the pan may spontaneously flame) 4) once the alcohol has cooked out, add some thick double cream (stirring continuously to avoid the sauce separating) 5) reduce temperature under the pan and let the sauce reduce down and bcome a really thick creamy sauce 6) serve over your steak and enjoy.
