Jeez, I didn't know ANY of that. Since I clearly don't know much about fish, I always just assumed I was getting what I was sold. I thought it was odd, if not a bit selfish, that when we took the sushi rolling classes we had one big question. Where the f*** do you get raw seafood that you can trust for sushi? His answer was "just put in an order here". Maybe he's saving us from bad fish, maybe he wants more money, maybe both? Either way I can't warrant a 1.2 hr drive (both ways) to get sushi supplies at top dollar. I'd love to see some testing of local sushi joints. " other fish" doesn't answer the question enough for me. Being land locked I always wondered what I was being fed from the sea.
