A homemade specialty of Ortiz, the Bonito del Norte is the most prized of the tuna family, appreciated for its pure white flesh, delicate texture and superb taste. Line caught, within a 24-hour period, the fish is cooked in seawater and the loins are hand-packed in olive oil and left to mature for at least two months. Serve as an antipasto, hors d'oeuvres, and part of Spanish tapas.
