Hi, Came on your question through googling – I’ve been puzzling on this one too. In the guidebook to Ischia ‘translation’ into English they mention a local speciality ‘linguine to the fruits of the sea’ containing mussels, clams, sea hypocrites and lupines. Googling leads to a lot of apocalyptic hot air. Common ingredients of seafood linguine include prawns (or shrimp) and squid. I thought they might do a local take on it with sea urchins, but that would surely be dangerous. I guess I’ll just have to go back to Ischia and seek out this dish with its wolf-like and ethically questionable ingredients!
