A baked macaroni and cheese recipe that uses a bechamel sauce is being highlighted for its ability to reheat without becoming clumpy, addressing a common problem with cheese-based versions. The recipe, published on a food blog, is described as the most luxurious of three macaroni and cheese recipes on the site, each with a distinct purpose.
The author explains that a previously shared hands-off baked mac and cheese, while easy and well-received, did not reheat well. Real cheese, the author notes, does not respond well to being melted, cooled, and remelted. A bechamel—milk thickened with cooked flour and butter—helps keep the cheese creamy and suspended. 
The new recipe, which the author says they heard about from "ten thousand people (and their mothers)," passed the reheating test, staying creamy.
It is positioned as a centerpiece dish for occasions when only the best will do, distinct from the site's quick stovetop version and the easier baked version. 
The author notes that the stovetop mac and cheese takes about three minutes longer than boxed, mostly for grating cheese, while the easiest baked version is hands-off and suited as a side dish for gatherings.
The new bechamel-based recipe is intended for when a more involved, luxurious result is desired.
