Bonito del Norte is considered by Spaniards the finest of tunas. Spanish fisherman pole catch large fish one at a time with live bait during the peak summer season in the Cantabrian Sea. The tuna is filleted by hand, and the white meat in tantalizing large chunks bears no comparison to American style canned tuna. Matured for a minimum of 6 months and preserved in olive oil for outstanding flavor and moisture retention.
