No, it is definitely rice, but they are round. We used to use them in a restaurant I worked at for desserts. They are a little more sophisticated than straight rice krispies, but give a similar affect of staying crisp in chocolate. I have seen them used on sushi and that is what they are originally intended for. I would like to buy some, but I don't even know what to search under.
well I will now be on the hunt for it in a sushi place and see what they say when i ask. I did do a quick search and found these suppliers of a variety of puffed rices. I have not used any of these suppliers and know nothing about thier buisiness but here is the link: http://dir.indiamart.com/impcat/puffed-rice.html
