About White rice koji

White rice koji is rice inoculated with koji mold and cultivated to produce a pale, fragrant grain used as a fermentation ingredient. The rice grains are typically coated with a soft, whitish growth and have a mild, sweet, cereal-like aroma.

It is sold fresh, refrigerated, frozen or dried, and used to make fermented seasonings and foods. Moisture and processing vary by form, so dried rice koji is not interchangeable by weight with fresh or refrigerated koji.
