Sea Urchin Linguine (Ricci Del Mar Linguine)
If any ocean creature can be said to have a cult following, it's sea urchin (uni). Its roe, the edible part, has a briny, sweet taste. When mixed with hot pasta, the roe melts and creates a luscious sauce, as in this recipe based on one from San Diego sea-urchin diver Peter Halmay. California produces most of the American sea-urchin supply; look for the top grade, called California Gold, or B-grade California Premium, which has a slightly softer texture. The roe is extremely perishable, so use it as soon as possible.
