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.
