Isesou Miyako Koji (Dried Rice Koji, Block Type) 200g — dried rice koji in the traditional block form, made from Japanese-grown rice. Isesou lays the koji into wooden koji boxes and works it by hand, sheet by sheet, which is what gives the block its shape. The maker's own suggested uses are amazake, shio koji and shoyu koji.
About Isesou
Isesou Co., Ltd. (株式会社伊勢惣) is a fermentation-foods maker based in Itabashi, Tokyo, incorporated in its present form in 1966, whose business is built on cultivating and fermenting beneficial microorganisms. Alongside koji it makes amazake, nukadoko rice-bran pickling beds, barley tea and miso-making kits.
What is rice koji
Rice koji (米麹) is steamed rice that has been cultured with koji mold, Aspergillus oryzae — the microorganism behind miso, soy sauce, mirin and sake. It is not eaten on its own: it is a fermentation starter whose enzymes break rice starch down into natural sweetness and protein into savoury depth. Block type means the koji is sold as a solid slab that you break up before use, as distinct from the loose, pre-crumbled granules sold in Isesou's 500g Loose Type pack.
How to use & enjoy
Rice koji is the starting point for several Japanese staples that are difficult to buy fresh in Australia. Shio koji is koji fermented with salt and water into an all-purpose seasoning for meat, fish and vegetables. Amazake is a naturally sweet fermented rice drink made by combining koji with cooked rice. Koji is also the key ingredient in homemade miso, and in shoyu koji, its soy-sauce-based cousin.
Ingredients
Rice (grown in Japan), koji mold.
