This is the finest tinned tuna belly in olive oil Perfect for a summer tuna salad The species of tuna is Albacore not the bonito as the name suggests This has nothing to do with cheap tinned tuna nor, confusingly, with the tuna known as bonito! This \'ventresca\' is the oil-rich belly fillet of the white tuna (also known as the albacore and in Spain as bonito del norte), in this case preserved in olive oil. This is a stratospheric delicacy at a rare price! Ours is from a venerated Spanish family company, Ortiz. We have tasted many and we think theirs is the best; the Lamborghini of canned tuna.
