Narutomaki: The Swirly White-Pink Japanese Fish Cake

Narutomaki: The Swirly White-Pink Japanese Fish Cake

Have you ever wondered what the white circle with a pink swirl is in Japanese dishes? Well, mystery solved. It’s a Japanese fish cake known as Narutomaki. 

This article will dig deep into the history of Narutomaki, its origins, how it tastes, how to prepare it, and why it is so popular as a ramen topping.

Where Does Narutomaki Come From?


The exact origin of narutomaki is unknown. The oldest detailed description of narutomaki was in a book called “Konnyaku Hyaku chin.” According to the book, people in the Edo period (1603-1868) in Japan wrapped narutomaki in kelps or tofu skin.

However in the book it is written about as an established style of kamaboko. This implies that its invention was earlier, but the exact time is uncertain. Before achieving national prominence in Japan as a ramen topping, it was famous as a topping for soba (Japanese buckwheat noodles). 

The name narutomaki, however, is a little less mysterious. There is a small water channel called the Naruto Strait between Awaji Island and Shikoku in southern Japan.

This strait is extremely narrow at only 1.3 kilometers and when the tide moves water from the Pacific into the Seto Inland Sea, it produces swift currents, forming many large whirlpools twice a day.

These whirlpools’ shape supposedly inspired the food narutomaki; the swirl of pink and white in the fish cake center represents water’s power and beauty in the Naruto Straits.

Narutomaki is made by wrapping undyed fish with white fish paste colored with red food dye into a log shape. The fish paste log is then cooked with steam to solidify and be cut into thin slices.

Narutomaki has a less fishy flavor and chewiness compared to ita kamaboko. The reason is that egg white and starch elements are mixed into the fish paste as binder elements, making the Narutomaki a little bit powdery and doughy, meaning the texture is closer to ramen noodles, creating a perfect combination.

Where Can I Find Narutomaki?
