Many recipes call for putting dry mustard into the roux when making mac and cheese, I think that’s pretty common. I have not tried putting regular prepared mustard into it, but I think I would probably like that. I love mustard and I love tangy mac and cheese!
As @Kardamom, my recipe for homemade mac & cheese calls for some dry mustard in the roux. It doesn’t add a terribly strong flavor. I wouldn’t add prepared mustard to prepared M&C though.
To make a proper cheese sauce you need to put a little mustard powder in to bring out the flavour of the cheese otherwise its really bland (or you’ll end up using too much salt).
Hmm, I don’t know how good that sounds…I might be surprised, I suppose. I like putting boiled hotdogs in it, and drown the whole thing in ketchup after lol.
@reijinni I saw that commercial and thought the exact same thing. Mac and cheese needs no mustard in it, or anything else extra for that matter. And it’s also kind of weird that the mustard bottle floats around in the commercial. I would be extremely confused and concerned if my mustard floated out of the fridge and put itself in my mac and cheese.
