Tara no Tazu Nabe is a traditional hot pot dish from Aomori Prefecture made with cod and its rich, creamy milt. In the local dialect, “tazu” refers to cod milt, also known as shirako in Japanese. The dish combines pieces of cod with milt and simmers them in a savory soy sauce-based broth, allowing diners to enjoy the rich flavors of the fish in one comforting meal.
Tara no Tazu Nabe is traditionally prepared during the winter to early spring spawning season, when male cod are filled with abundant milt. During this period, the milt is especially rich and creamy, making it an ideal ingredient for a warming hot pot.
As the cod and milt simmer together, the milt adds a deep richness to the broth. At the same time, the cod meat releases its natural umami, creating a flavorful soup that allows you to enjoy the character of the fish from both the meat and the milt.
Among the seasonal varieties, cod caught in January is particularly prized. The cold winter waters help produce fish with excellent flavor, while the male cod contain generous amounts of milt during the spawning season.
The combination of tender cod meat and smooth, creamy milt makes this hot pot a particularly satisfying winter dish. The warmth of the broth also makes it especially appealing during the coldest months of the year.
Cod milt, or shirako, is used in many different Japanese dishes. It may be served fresh as sashimi-style cuisine, grilled with miso, dressed with vinegar, or deep-fried. Because it is commonly prepared in these ways, enjoying cod milt in a hot pot is a somewhat less common experience.
For this reason, Tara no Tazu Nabe offers a special opportunity to discover another side of this prized seasonal ingredient. The milt gradually enriches the broth as it cooks, creating a creamy depth of flavor that complements the delicate cod.
The cold-season cod used in this style of cuisine is landed in several northern fishing areas, including the Pacific coast from Hokkaido to the Sanriku region and the northern Sea of Japan. The availability of fresh local cod has helped make dishes such as Tara no Tazu Nabe an important part of the winter food culture of northern Japan.
December through February is the main season for enjoying Tara no Tazu Nabe, with January being especially recommended. If you visit Aomori during the winter, this traditional hot pot is well worth trying for its rich broth, tender cod, and creamy seasonal shirako.
