Uni is the Japanese word for the edible part of the sea urchin. At some point, you must have met a member of its devoted following. While it’s soft, briny, and rich, many consider it to be too rich. It’s a flavor that hits fast, while the texture is somewhere between foam and jelly. Just for a second, it may give you a feeling of adventure, but if you are a newcomer, you’ll probably struggle to finish a full bite without blinking.
