I was at the grocery store today and I wanted to get some sweet potatoes... but the only sweet potato I saw was white... and I saw an orange "yam", but I was fairly certain that was a sweet potato. So I did the only reasonable thing and called my sister. She knows stuff like this. She explained that orange "yam" was most likely a sweet potato and to grab it no matter what the name actually said, it was what I was looking for. She was right, and the sweet potato egg nests were delicious.
Fast forward to this evening when my Daily Doodle has become a looming must-do instead of the happy let's-do it was this morning. (I have a tendency to procrastinate. I get up early and feel like the whole day is ahead of me and what a glorious day it will be, only to spend it thinking about cool stuff I'm going to do, and making fun letters to send, and then it's dark and I realize I still haven't done my Daily Doodle I was so amped about at 6am). Healthline.com explains "yams" aren't exactly a common item in the grocery store as they would have you believe, in fact they are more than likely some variety of sweet potato. Low and behold, I saw pictures and agreed, "yams" aren't yams at all, and Healthline was correct, I have not actually seen a yam, but rather a few different varieties of sweet potatoes.
A yam has brown, rough, bark-like skin. The flesh can vary in color from white and yellow to a deep purple. A sweet potato has smooth skin (think potato) that can be a variety of colors including white, brown, yellow, and reddish purple and the flesh color can also vary.
