La Bottarga Cagliaritana

The Phoenician port of Karalis is Cagliari and, sitting on the island’s southern verges on the Gulf of the Angels, it seems not of Sardegna. The Sards who live away from the port say it is a place doubled-faced and call the Cagliaritani hollow-hearted. They say Cagliari is of the world and not of Sardegna. Sardi falsi—sham Sards—they are called. Surely discordant, as a city, with the Stone Age commonweal of the island’s interior, Cagliari’s most pleasant quarter seems the one raised up in the serene, medieval tracks of the Pisani. There, embraced by walls, new—as measured in Sard antiquity—one senses, still, some sweet press of sympathy. And it is there on its piazzette, where one can sit under broad, blue-striped umbrellas, to sip at cool Nuragus di Cagliari between melting bites of salty bottarga, the Sards’ caviar. Fashioned from eggs harvested from the cefalo—the gray mullet—the roe sacs are taken whole, compressed under thick hefts of marble, rubbed with unpounded crystals of sea salt, then left to dry on grass mats under the Cagliaritano sun. What emerges after several months of patience is a supple, glossy mass that, when shaved or grated gives up an authoritative yet balmy brininess. In the humblest of osterie as it is in the ristoranti, this bottarga, the Sards’ caviar, is presented with simple adornments. Rather easily hunted up in American specialty stores, look, though, for the bottarga di cefalo rather than the more common, far less delectable, bottarga di tonno, made from eggs of the tuna. Here follows a recipe for a most uncommon, sensual sort of overture to lunch.
