I've had Mochi before. I do aikido, and absorbing a bit of Japanese culture tends to be part of the art.
For those not in the know, Mochi is a sweet snack made from sticky rice, pounded until it is gummy and pasty, usually filled with some sweet filling. The texture is not my favorite.
They have standard Mochi in Kauai, but they also have a variation which I like much more. They add baking powder, and other things like pumpkin or chocolate, and it comes out somewhere between banana bread and jello-laced brownie.
We had it as a quick snack before our trip through the canyon.
