Gourmet mac and cheese- any favorite cheese combinations?

Yes, H likes it, and when I’m buying, I’ll go for the premium brands, full fat.
I do like that sometimes with lots of black pepper on it. I’d be willing to give the NYT recipe a try using CC that @shrinkrap posted about. Thanks for weighing in @retrospek, don’t think a lot of people are clued in to the full fat stuff.
