This was perfect! I only had 2 cups of macaroni so I added less milk to the roux so it was thicker and clung to it really well. I was out of dry mustard so I just added a bit of yellow mustard and it worked perfectly. Thanks so much for posting this recipe - it will be the only way I make mac and cheese in the future! DELICIOUS!!!
Delicious! It is a keeper. Posters on Pioneer Woman's own site suggest less mustard. Start with I teaspoon and work up. If you don't like mustard go with one. If you do go with two. Use cheddar or it is good with a mixture of whatever you have cheddar, Parmesan, jack etc. Creamy roux makes the base consistency perfecto. Love it and so did my cheese loving kid. Thanks for posting. Enjoy! ChefDLH
