This delicious tin of tuna has something of a cult following and is a special treat. Ortiz bonito tuna (Thunnus alalunga) is a smallish tuna generally weighing less than 20kg. All of the fish that Ortiz buy is caught on rod and line in the Bay of Biscay and then processed by hand.

The flesh is a pale colour and has a delicate flavour that is at its best when eaten simply, in a salad for example.
