Negima-nabe, a tuna-and-onion stew, is a tradition handed down since the days of the shoguns. At a time when lean meat was treasured, this stew was contrived as a way of lightening the texture of toro, the fatty cut of tuna. Enchanted with Edo-era cooking, the proprietress of Negima revived it. True to original recipes, the dish uses neither kombu nor mirin. The meal ends with ‘pepper rice’, a dish of fresh-cooked rice seasoned with broth from the pot and pepper. Sample the pure cooking that true Edo-ites have always loved.
