"Toronto fish and seafood wholesale distributor Daily Seafood sells a direct-to-customer make-at-home sushi kit called Sushi Master. It contains saku salmon (a precision-cut block of the loin, perfect for slicing), yellowfin tuna, hiramasa (kingfish), otoro (tuna belly), along with ikura (salmon caviar), gari (pickled ginger), nori and wasabi. For a modest fee, you can add a tray of Boston uni."
