This recipe was shared by a co-worker who found it in a newspaper. It was touted to be the recipe for the famous Macaroni and Cheese served at the Soho Grand Hotel in New York City. There is another recipe posted on this site that also claims to be the Soho Grand's recipe, but it's different. I've never been to the Soho Grand, so I can't say if either of them are the right one, but I can tell you that this recipe is absolutely delicious. One of the best mac and cheese recipes I've tasted to date.
05Gradually add milk to the flour/butter mixture, stirring constantly. Cook and stir for 2 minutes. Add mustard, nutmeg, salt and pepper.

06Combine the cooked pasta and the cheese sauce and pour into a greased 4 quart baking dish. Sprinkle 1/2 the Parmesan cheese over the top, then sprinkle the rest of the shredded cheddar, then the rest of the Parmesan cheese.
07Bake at 400 F about 20 minutes, or until lightly browned and bubbly.
