OK, here's one cross-cultural experiment I don't think you'll find in the U.S. anytime soon: The Burger King Hot Taro Pie.
Taro root is pretty bland, so they've helpfully added a lot of sugar. The result is a pile of creamy-mushy stuff in a fried shell. It's good if you like that kind of thing, which I do. What's off-putting is the purply-gray color of the filling; it looks like some kind of industrial material.
