Tokyo's Tsukiji market is a must-visit destination for any food lover. You'll find not only fresh fish here, but everything you need to create a Japanese meal, from all over the country. In this program we introduce some special Japanese ingredients such as Katsuobushi, or bonito flakes. Shaved from rock-hard slabs of fermented fish, the flakes are used in the soup base of almost every Japanese dish, and are the essence of the umami taste. We will show you how they're made, and the secret behind their magical flavor.
