No, it's not my mama's but my sisters! This is a unique recipe that requires no roux so the sauce is creamy not grainy as some can be. I make "Grown Up Mac-n-Cheese by replacing some of the cheese with gorgonzola (4oz to be exact) and giving it a crumb topping instead. This is easy enough for you to do as you like. I do recommend using several different types of cheese for complexity.
