【Nigiri sushi: Gyoran】
Murasaki uni (Northern sea urchin) is distributed a little more south than Bafun uni and on occasion in Sagami Bay. On the Pacific side of Japan, this species inhabits the area from the Sanriku region to Hokkaido. It is usually a dark purple color, but some can be slightly brownish. The spawning season is from September to January.
Sea urchin with fine texture and ocean flavor is meltingly delicious. Creamy and sweet aftertaste. Unlike salmon roe, the seaweed flavor loses a bit of the delicate sweetness so there are some sushi chefs who rarely make sea urchin in Gunkan-maki.
