I first heard about cod sperm, and how it's an edible delicacy for the "jet set," back in December. Socialite wrangler Gilt City threw an upper crust mingle fest at Benu. Chef Corey Lee decided to serve a liquified version of cod sperm in shot glasses as a passed appetizer. The well-to-dos knocked it back and liked it with reckless abandon (even though most of them didn't know what they were sipping). And the Chronicle's Beth Spotswood wrote about the affair and her server's insistence that "it's like a thing. It's the male version of caviar."
