The theme this episode is grilling. Tuna is very popular served as sashimi, but it's also delicious cooked. Chef Saito and Yu Hayami make 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 the side dish, they cook green bell peppers, a summer vegetable, and season them with umeboshi pickled plums and nori seaweed, for a deliciously Japanese flavor and aroma.
