I do sushi at home pretty frequently. No chance of sushi grade fish around here, in the middle of Missouri, so everything is cooked. (I was amazed to find nori and sushi rice at the WalMart!)
I like to use that phony Krab stuff, smoked salmon, shrimp, shredded carrots, cucumber, asparagus--not all at the same time, of course.
If I go out, I like smoked eel, but I have only had raw fish once. I didn't care for the texture, but I would try again. I don't like avocado in sushi rolls because of the texture, either.
