different colors of sea urchin roe
What is uni? Uni (oo-nee) is the Japanese name for the edible part of the Sea Urchin. While colloquially referred to as the roe (eggs), uni is actually the animalâs gonads (which produce the milt or roe). Uni ranges in color from rich gold to light yellow, and has a creamy consistency that some love and is off-putting to others.
