I really like potatoes. Such a versatile tuber. Is there anything you can't do with them? Boil em, mash em, stick em in a stew?
rofl. Potatoes are a part of supply in most of the world. 
It's quite a basic food staple, I would think. Lot of energy packed into a little bit of food.
I agree.  The potato was introduced to Europe in the 16th century. They are from South America.
