That looks delicious.
This is the rice I'm using:
The first few ended up being somewhere between a temaki and a small ice cream cone in shape and they are definitely overstuffed.
I made a few oversized maki rolls with egg and a bacon strip afterwards that was surprisingly well-packed considering I don't have a bamboo sheet to form with and no idea how to do it.
I have a lot of improving to do but it was very fun and the rice was the star of the show.
