I walked by J-Town recently, went into their fish store "Sakana-Ya" and saw a big selection of Uni "Sea Urchin" in the fish counter. There are selections from Voucouver and Hokkaido Japan. They look ok from the packaging.
The uni from Voucouver are out of season at this moment, so I picked up a tray of the Japanese Uni as I have a strong mood for it at that moment, after tasting some of the super fresh uni just arrived from Boston at Kumai of Mississauga the night before. However, the taste of it is not so fresh, even worst is when we finish the first layer of Uni, those in the second layer does not look right as the colour is uneven and kind of dark with a loose texture, we tried a little and found out they have a smell of chemical with a bitter taste !!
We threw the rest to the garage bin and I swear I will never touch any fish at Sakana-Ya.
