Katsuo (鰹)
Katsuo is a member of the bonito family and is characterized by its sharp teeth, but have you ever wondered what kind of fish it is? So, this time, let’s explain about Katsuo. We will also introduce how to eat it deliciously, so please check it out below.
WHAT IS KATSUO?
Katsuo, a prefectural fish in Kochi prefecture, is an ingredient that is eaten daily. Generally, this kind of fish has a total length of about 40 to 60 cm, and when they grow, it will grow up to a total length of 1 m and a weight of about 20 kg. It is a type of sashimi that is cut into knots where the surface or the outer part is boiled. The most popular menu using Katsuo is the “Katsuo no Tataki“, also known as Bonito Tataki. Katsuo no Tataki is a nationwide menu, but in Kochi prefecture, the ingredients and recipes differ slightly depending on the region and village.
ORIGIN
Kochi Prefecture boasts the highest consumption of katsuo in Japan. It was designated as a “prefectural fish” on June 21, 1988. This fish is known to be a fierce fighter when they are hooked.
Katsuo usually schools off the coast with other pelagic fish like tuna and albacore and fishing for bonito occurs offshore in 300-600 feet of water. There is a theory that said that the dish katsuo no tataki generally came from the fishermen who had eaten the caught fish called katsuo on board.
At that time, there was no preservation technology and that resulted in the development of a cooking method called “tataki” to make use of the katsuo that had lost its freshness on board. They first skewered the fish and then grilled the surface or the skin of the fish because they believed that the parasites under the skin of the fish are easily killed and can be eaten afterward. Before katsuo no tataki was named in Kochi prefecture, the 12th feudal lord, Toyosuke Yamauchi, named it first as “salted bonito” and “shutou”.
HOW IS KATSUO MADE?
Process of Making
Kochi’s traditional fishing method has continued since the Edo period. The taste of it is much better when doing the traditional single fishing rather than the net fishing where the fish struggles so much that might affect its meat. The katsuo season comes twice a year, in spring and autumn. Spring katsuo is called “first katsuo” and autumn is called “return katsuo”. During these seasons, many colorful katsuo are all lined up at supermarkets and fishmongers.
There are many ways to eat it, but among them, katsuo no tataki is much more known to many Japanese locals. It is made by grilling the surface of the katsuo because ideally, only the surface should be burnt and the inside should be almost raw. The advantages of roasting the surface are that it has a fragrance similar to smoked food, that excess water in the body is reduced, the texture is improved and the taste is rich, and the thin fat that is attached between the skin and the body. Adding plenty of condiments such as onions and Japanese ginger depends on one’s taste.
The condiments and sauce differ depending on the store and region. By having this menu called Katsuo no Tataki, it makes the fishy odor peculiar to katsuo reduced. Also recently, “salt tataki”, which is eaten by sprinkling salt on baked bonito while it is warm, is very popular.
The Uniqueness of katsuo
In the average year, the amount of katsuo consumed per household in Kochi City was 5,163g, which is far behind the others and is the highest in Japan. Katsuo no tataki is a popular menu on the table. Not only sashimi but also the nationally famous katsuo no tataki is a popular menu on the table.
The essential thing in distinguishing delicious one is the color of the meat. The brighter the red color is, the more it is fresh. If the meat looks dark and cloudy, it already oxidizes and has lost its freshness. For those who want to try it with fat, it is recommended to pick the katsuo with light pink fat between the meat. Clear eyes and clean red gills are also proof of freshness. it also has taken root as a dietary habit throughout the prefecture and is also a standard dish of “dish bowl dishes” that are indispensable for ceremonial occasions and Shinto rituals.
