This is a dish that comes from Long Island, New York, not the Big Island of Hawaii, a Northeastern take on a Pacific classic. I’ve made it with Atlantic bonito caught offshore and yellowfin tuna bought at the market, the meat trimmed, cubed and mixed with sesame oil and soy sauce, a little chile-garlic sauce and lot of chopped scallions. I top the salad with roasted macadamia nuts and a few vigorous shakes of furikake, a Japanese seasoning that is made of sesame seeds, dried fish and seaweed, salt and sugar. It makes for about the most delicious eating in the world.
