In this article, we will delve into the world of tuna toro, exploring its origins, characteristics, and the reasons behind its exclusivity and high demand.
Introduction to Tuna Toro
Tuna toro is obtained from the belly of the bluefin tuna, specifically from the species Thunnus thynnus, Thunnus orientalis, or Thunnus maccoyii.
