Carroty Mac and Cheese

I have to admit that when I first tried this dish, I wasn't overly impressed. It was good, but not what I want from macaroni and cheese. I'm one of those people who loves a rich bechamel sauce, but this is not that dish. This is more of a custard, less cheesy. It reheats nicely though (especially if pork juices get all over it while it's reheating). It's also an amazing way to use up excess CSA carrots, so up it goes.
