What's in a name? Well, for starters, sweet potatoes aren't really potatoes -- they're actually in the morning glory family. And yams are in a genus all their own, more closely related to lilies than spuds. The naming confusion can be traced to the American South in the 18th and 19th centuries, when African slaves encountered the sweet potato and naturally linked it in their minds with their native yam. But they're both delicious no matter they're called -- nomenclature aside, today we take a close look at sweet potatoes and yams.

Nicholas gives us a noble use for leftover sweet potatoes, a kid-friendly baking project, and a better turkey sandwich.

Jenny shares a holiday dish that brings up a lot of memories. 

Cleo and Julia make sweet potatoes two ways -- salad and soup.

The many ways sweet potatoes will keep the kids (and you) well-fed.

The last time we saw Charlie, he was making some pretty forward advances at Merrill's little girl, Clara. (Don't worry, they're still friends.) Today, we get a very special look at Charlie as he gobbles down a meal. On the menu? Kale and sweet potatoes from Lucky Dog Organics in the Catskills, a favorite of Charlie's dad Peter.

Orange foods (sweet potatoes, carrots, cantaloupe) are a big hit with Charlie. Then why dress him in white onesies, we asked? "They're specifically to make these early meals so photogenic," Peter told us, and we can't help but agree. Enjoy the above photo of Charlie with his mom Sarah -- soon he won't look so clean!

Jenny's got a new favorite recipe, and she's not sharing the leftovers.
