The theme this episode is blanching.Sashimi is a popular Japanese dish best known as fresh seafood, sliced and served raw with soy sauce. In this episode, though, chef Saito and Yu Hayami serve blanched sashimi on a bed of shira-ae sauce made of tofu, sesame seeds, soy sauce, and more, to dip and enjoy. For the side dish, they make bamboo shoots with powdered bonito fish. When shaved into flakes, dried bonito is a crucial ingredient in the dashi stock at the heart of Japanese cuisine. They also use powdered bonito, sprinkling it on at the end to provide even more of its delicious flavor.
