So-named because in cross-section, its scarlet tuna filling resembles a red-hot iron bar (tekka meaning ‘red-hot iron’). Arranged with the cut surface uppermost, the bright red of the tuna contrasts brilliantly with the white of the rice and black of the nori. The almost startlingly bloody aroma and flavor of the irony-rich fish combines with the delectable sweetness of the nori to create a taste sensation in a class of its own. And while the red flesh of tuna is itself to be relished, tekka-maki filled with the medium-fatty chu-toro and premium o-toro belly meats are an indulgence one step further. Nigitoro rolls, made with well-tenderized toro, scallions (negi) and a generous dose of wasabi, are an even more popular choice.
