It tastes better the next day
Alton Brown, on one of his shows, explained why things like stew meat actually are better after they've been cooled and reheated again. But it's something I've been hearing since I was a kid, and there are plenty of things that I think are better after a rest in the refrigerator. Like soups and stews -- things where you want the flavors to "marry."
So, do you believe it, too? Are there foods that you think are better after they've spent a night in the fridge?
