Assuming a big city on the Easter Seaboard in the U.S. with a fresh fish market, what would you say are the best bets for sushi-grade freshness when it comes to types of fish?
What I have done before is buy a tuna steak and smell it before and also make sure it doesn't have the rainbowy sheen on the surface -- never got sick. Do you know of other types of fish that are typically fresh enough at fish markets that you could use to make sushi?
