This was the absolute best macaroni and cheese ever! It did take awhile to put together and cook but it was so worth it! The only thing different I did was use almost 4 cups (2pks) of cheddar cheese, instead of the 2 cups the recipe called for. Oh, and I did not use the mustard at all. I took that out completely. Other than that, it was very easy, my kids and husband loved it. I will never make boxed mac & cheese again!!!
