WHAT IS IT?

What exactly is Sea urchin (uni)?

Uni is the edible gonad of sea urchin, not “urchin eggs.” Species, seaweed diet and post-harvest treatment strongly affect flavour.

CHOOSE WITH CONFIDENCE

Place Sea urchin (uni) beside two close relatives.

Compare Salmon roe (ikura) for taste—Salty, rich and marine—and Herring roe (kazunoko) for texture—Distinctly crisp, many tiny eggs together. Set each beside Sea urchin (uni), one plate at a time.
