That is probably the most fantastic thing I'll hear today. I never thought of potatoes as emergency food (unless they're in their "french fried" format)!
All this talk of sweet potatoes is making me want one.... I haven't had one in a couple of months I think.
Now my question is -- I can only ever find GIGANTIC, 2-lb sweet potatoes in my grocery store. We're talking the size of a grown woman's foot. Just huge. Are you able to find more sanely-sized ones? Or do you cut them up and portion them out? I never know what to do with the monstrosities I'm forced to buy at my Kroger...
