It wouldn't be Thanksgiving without cranberry sauce. Think about it: when it's not Thanksgiving, and a restaurant sells a turkey sandwich, it's merely a "turkey sandwich." But when they add a layer of cranberry sauce in it, it's easily called a "Thanksgiving sandwich." Turkey may be the centerpiece of the Thanksgiving meal, but it's the cranberry sauce that makes it Thanksgiving, even if there are many side dishes. And yet, cranberry sauce is a weird thing. Many people, for the kitsch or irony, simply buy it in the vintage canned form, where it comes out in the same exact shape as the can-little grip ridges included. Others make cranberry sauce from scratch. Either way, you'll probably have some leftover.
