I taught a mini sushi class to very young kids in September. There are no action pictures as it was barely managed chaos the entire time. The kids had a blast and ate every roll they made.
There have been several requests to teach this as a full blown class, so keep an eye out for a hands-on winter sushi class.
When working with sushi mats, I typically wrap them in saran wrap to keep the rice from sticking to the mat. For this class we tried out non-stick sushi mats as well. They have a different feel, but made clean-up a snap. I have added them to my Amazon store along with my other favorite kitchen gadgets.
