It Just Gets Bigger and Bigger as It Cooks! "Basho Senbei," a Specialty of Osaka!

This video shows a demonstration of baking basho senbei at a festival stall.

Basho means "banana" and basho senbei (rice crackers) are named after the shape of a banana leaf.
It's pretty uncommon to find even in Japan, but it's an Osaka specialty, and you can buy it online as well.

In the video, you can see the rice cakes that start out the size of the palm of your hand getting bigger and bigger as they're cooked. Be sure to check it out!
