When you go to buy potatoes you generally just have to pick a color or a name, because whether they're red, russet or fingerling they're all called potatoes in the end.
But their tuberous root cousins are named sweet potatoes and yams even though they seem to be as similar to each other as two different kinds of potatoes. So what's in a name?
Watching this helpful animated short created by Eva Hill should clarify all the differences between sweet potatoes and yams you need to know, but at the end of the day if it's baked then covered with butter it's all good!
