Our theme this episode is grilling. Tuna is very popular served as sashimi, but it's also delicious cooked — we'll be making goko-yaki, seared rare tuna with plenty of sesame seeds, and named for its "five aroma" sauce. The sauce is made with five ingredients — myoga ginger bud, shiso, natto, and more — with refreshing flavors that make this a perfect dish for summer. For our side dish, we'll be cooking green bell peppers, a summer vegetable, and seasoning them with umeboshi pickled plums and nori seaweed, for a deliciously Japanese flavor and aroma.
