Kojiya Koji Miso

Koji miso is miso with a high amount of “koji,” which is made by attaching koji mold to steamed rice, soybean, or barley. The Kojiya Koji Miso is made by fermenting soybeans with koji that was cultivated using a traditional, hundred-year-old recipe. It is rich and full in flavor, bursting with umami goodness.

You can use Kojiya Koji Miso can be used in the usual Japanese foods, like miso soup, miso katsu, with udon noodles, stir-fries, sauces, and marinades. But you can also use miso for a number of non-Japanese foods, like to enhance tomato or meat-based sauces, or in soups and glazes.

Miso was introduced to Japan by Buddhist priests from China more than a thousand years ago. As with many ancient foods, the fermented mixture of grains, salt, and soybeans was a way to preserve food. The original soybean paste from the Chinese transformed to become miso and shoyu in Japanese cuisine, two ingredients that mark Japanese food.

Because it often contained rice—a luxury in ancient times, miso was considered a delicacy, and thus only enjoyed by the nobility. Eventually the Samurai made it a staple in their diet as well, for its energy-giving properties. Miso had classist origins, too, as the rice miso that the nobility and the samurai consumed were made with the most expensive polished white rice. The peasants and farmers were not allowed to use their harvest to make their miso, and so had to make do with broken rice, barley, and other grains. The darker miso, therefore, gained a reputation as the “poor man’s miso.” But by the mid-14th century, miso had gained much popularity and ingredients were easier to come by, and it was enjoyed by everyone, regardless of class.
