japanese sweet potato

This is something I've never seen before -- red on the outside, snowy white on the inside, and very sweet indeed.

I bought one yesterday to put into the hot chicken curry I was making, which is now hot and sweet, and made even sweeter when one uses raisins as a topping.

I think I like plain old russets better in this dish, but I'll be buying Japanese sweet potatoes again, if for no other reason than they're such a pretty tuber.
