This is really an easy sauce that is made off the base of my Béchamel sauce recipes. You can use either:
I use this cheese sauce if I am going to make any baked dish that requires cheese sauce (eg lasagna, mac & cheese etc). It is also great to make a cheese sauce for burgers, or if you like a cheese sauce for steak.
You can also add cooked button mushrooms to give you a delicious cheese and mushroom sauce.
