"This dish came about while playing around with the idea of pairing prosciutto, which is basically cured and dried pork, with melon," says Pepperell. "We thought cured and dried kingfish could be an interestingly happy alternative." Start this recipe two days ahead to cure the kingfish.
Note You'll need to order kingfish top loin ahead from your fishmonger. Finger limes and blood limes are available from select greengrocers. If they're unavailable, substitute lime or lemon.
