Callipo Buzzonaglia Di Tuna with sunflower oil (620 g box) The Buzzonaglia is the part of the fillet that is located close to the central bone, the backbone of the fish. It has an intense flavor and a dark color and is appreciated above all for its softness. The Buzzonaglia di Tuna is the least part of the tuna compared to the botargo, lettuce and the remaining parts and the part of the meat closest to the belly and underneck, therefore darker. In the past it was a typical seafood dish. It is best combined with a tomato salad, perhaps seasoned with a good sweet Tropea onion, chilli pepper, olive oil and plenty of lemon juice, to make it more digestible.
