What is Sagohachi duke?

Sagohachi duke is a type of pickle made with a special mixture of salt, koji (malted rice), and rice. The name “Sagohachi” comes from the Japanese numbers three, five, and eight, which refer to the ratio of these ingredients: 3 parts salt, 5 parts koji, and 8 parts cooked rice. This simple mix creates a paste, or “nukadoko,” that locals used to pickle vegetables, fish, and meat.
The process is similar to making other pickled foods, but the koji gives Sagohachi-zuke a unique, slightly sweet flavor. It’s popular for being a simple way to preserve food while adding a deep, umami taste. The result is a savory and healthy side dish or a way to make main dishes more flavorful.
A Short History

The history of Sagohachi duke is somehow related to the Tohoku region of Japan, particularly in Fukushima and Akita prefectures. People believe it started as a smart way to use leftover rice and koji from making sake (rice wine) or miso. This method became popular in farming communities as a way to preserve food during the cold winters. It was a practical and tasty solution that helped families get through the seasons when fresh vegetables were not available. Over time, they passed down the recipe through generations, and a lot of Japanese still loved this and become part of Japanese home cooking and local cuisine today.
