大とろ | Strong fatty tuna
The “strong” fatty part of the Tuna (Maguro), o-toro is Poseidon’s chocolate cake; filled with marbled fat, straight from the upper belly. There’s no harmony here, but there doesn’t need to be: those receiving (or ordering) this expensive cut know exactly what they’re after. Like other cut of the Tuna, the appearance of O-Toro changes season to season, part to part (e.g. from the front or middle of the tuna) and Tuna to Tuna.
