there are so many different varieties out there. In all colors and sizes. What you can buy in the store here is just 2 maximum 3 varieties. Btw. if it says yam in the store - it is still a sweet potato :)

Well, I have seen the sweet potatoes in the grocery store, but they sure didn't look like that one! I read an article about yams once, so I did know the ones in the store aren't the real thing. But I suppose I will go right on calling them yams, because that's what I've always called them.
