Shaved dried tuna – Katsuobushi may not be fresh, eye-catching, or as soft as stone, but it is the essential ingredient that gives Japanese dishes their signature flavor.
Katsuobushi imparts a distinctive umami flavor
Katsuobushi is made from skipjack tuna, a fish rich in inosinate – a compound responsible for the deep umami taste. When paired with the glutamate from kombu seaweed, these two compounds create a burst of umami flavor, offering a unique culinary experience.
Umami is the fifth taste, alongside the four basic tastes: sour, sweet, salty, and bitter. Umami is described as a savory sweetness, akin to the flavor of broth made from vegetables and fruits. In other words, it’s the natural sweetness of vegetables, fruits, meats, and seafood. This special flavor helps to harmonize the other tastes, bringing balance to a dish’s overall flavor profile.
The process of making Katsuobushi
The tuna is filleted and simmered before undergoing multiple rounds of smoking to create Katsuobushi. The firm tuna blocks are then shaved finely to achieve a perfect shape and are left to ferment. The fermentation process involves the use of Koji, a beneficial microorganism known for aiding digestion and promoting health. This same microorganism is also found in Miso and soy sauce. To achieve the desired hardness, the fish is sun-dried for several months, creating wood-like flakes with over 80% of the moisture removed. This process makes Katsuobushi one of the hardest foods in the world.
Uses of Katsuobushi
In Japanese cuisine, Katsuobushi is commonly used to make kombu dashi, a traditional Japanese stock, and is also used as a topping or garnish for various dishes. You can add Katsuobushi to dishes like noodles, eggs, rice, vegetables, and tofu to enhance the flavor. A traditional dish features hot rice topped with tuna flakes, which curl up and dance when absorbing steam.
Many Japanese chefs prefer to buy whole Katsuobushi and shave it themselves using a special tool. While dried tuna flakes are available in Japan, most home chefs purchase pre-shaved flakes in bags. These flakes are then added to broths or used as a garnish for various dishes.
Buying and Storing Katsuobushi
Katsuobushi can be easily found in Japanese or Asian grocery stores. Additionally, it is convenient to purchase online from various retailers. The dried tuna is available in either block form or pre-shaved. To store Katsuobushi, simply keep it in an airtight bag or container in a cool, dry place. When stored properly, it can last anywhere from six months to a year.
Katsuobushi has become an essential ingredient in everyday dishes, enriching and enhancing the flavors of Japanese cuisine. To truly experience the essence of Japanese culinary tradition, don’t miss the opportunity to incorporate Katsuobushi into your meals.
