As unpleasant as it is to step on a sea urchin, these creature of the sea are edible, and tasty. One of my favorite foods is the sea urchin, eaten straight out of the shell. The strong brine-y flavor isn’t to everyone’s taste, and it is rather rate to find them offered in restaurants in the United States. However, processed sea urchin, called “uni” in Japanese restaurants, is everywhere. It has a very buttery taste and it’s delicious.
