John,
The sushi looks delicious. If you can find one-- there is a special wooden sushi rice mixing 'barrel'/bowl with a copper band around it, that you put the sushi rice in to mix with the rice wine vinegar and mirin. You are supposed to fan the rice as you stir it to cool to get rid of any excess moisture (but you probably know all this so I am preaching to the choir). I've tried doing this myself but it really is a 2 person operation -- I'm just not that co-ordinated -- it feels alot like patting your head while rubbing your stomach. My husband grew up in Japan and is really particular about his sushi, but my stepson says 'Linda's sushi rules!'
