Have you ever eaten gonads? Well, if you've munched down on some uni, then the answer is yes.
In culinary terms, must of us understand uni to be the Japanese word for sea urchin. But actually, it's more specific than that -- uni is a sea urchin’s gonads. The gonads, which produce roe (another delicacy that many of us enjoy) are the only edible part of the sea urchin and are often served at sushi restaurants. The delicacy is usually served raw, and its smooth texture and briny, creamy taste makes it quite versatile in the kitchen.
Though it was once only a feature at Japanese haunts, today uni appears on other menus atop pasta, on sandwiches and even as an accompaniment to bone marrow.
