Related article Recipes hat Uses Koji Rice Shio Koji, also known as Salt Koji, is made up of rice koji, salt, and rice. Shio koji has been widely used in Japan with ancient origins as a seasoning or ingredient, particularly for fermented foods. Related article How to Make Amazake Amazake (Sweet Sake) is a Japanese energy rice drink made from koji (Aspergillus Oryzae) and rice. It is known for its health benefits since Japan’s Kofun Period. The Benefits of Handmade Koji Rice You know exactly what ingredients are being used. Formerly, miso, shouyu, amazake, etc., were homemade with koji in the Japanese family. However, eating habits change with time, and miso, shouyu, amazake changed from "things to make" to "things to buy." Under such circumstances, many people are uneasy because they don't know what type of rice is used in foods such as miso and shio koji (salt koji) available at supermarkets, etc. If it's handmade, you can make it with pesticide-free rice prepared by yourself, so it's safe. Handmade is fun! When Kawashimaya's staff tried to make handmade koji rice, they were impressed that their hands became so smooth. It's a famous story that because they engage in sake-making, the hands of a chief brewer at a sake (Japanese liquor) brewery are beautiful. In koji rice's nutrients, there are a lot of components that make the skin beautiful. Then, if you make koji rice by yourself, you will take care of it like your own child. Thus, the miso and amazake you made will become more delicious. It's more economical. When making miso, you will need koji in kilograms. If you buy it, it will be really pricey. For that, if you make your own koji using a koji starter (Aspergillus oryzae), it will be much more economical because you can even make koji rice from 15kg of rice. The Steamed Rice, is What Determines the Quality of Koji Rice If the rice used in koji rice making is cooked with a rice cooker or the like, the amount of water (60% or more) becomes too much, and it won't be finished as good koji rice. In order to make the rice with moderate water content (about 38%), it's necessary to "steam" the rice with proper steam. The koji-making professionals make steamed rice with a bamboo steamer (seiro). Furthermore, by using a steaming cloth made of tetoron, the time loss (temperature drop) caused by the rice sticking on the cloth can be eliminated so that you can do the seeding step (sprinkling the koji starter on steamed rice) smoothly. Koji-making Professionals' Favorite Tools! Koji-making's Best Friends Tetoron Cloth Strong against high temperature, excellent in steaming. Rice won't stick to the cloth, a convenient steaming cloth. It's also useful for moisture control during the warming of koji. Seiro (Bamboo Steamer) Steamed rice is the key to making koji. Using bamboo steamer/seiro, steam the rice with high heat for about 40 minutes. It's also a helpful tool for daily dishes. Tips for Making Steamed Rice from the Professionals A bamboo steamer is recommended to steam the rice! Cover the steamer basket when steam/vapor comes out from the surface of the rice and the surfaces become transparent. Steam it for about 40 minutes (recommended) after putting on the lid. When steaming in the bamboo steamer with two or more rows, change the order of rows midway through the steaming process.

The amount of koji starter is about 1.3g-10g for 1kg of rice (rice for raw material) (about 0.2g-2g per 150g of rice). If you are still not used to koji rice making (first-time try), it's better to use the koji starter more. Because even if you use much of it, there will be no problem. About the finised amount: ・ The steamed rice will be 1.8-2 times heavier than the original/raw weight if you steam the rice.・ Then, after the koji rice is completed, the weight will be 0.9 times the weight after steaming. Thus, the finished rice koji will be 1.62 (1.8ｘ0.9)～1.8 (2ｘ0.9) times from the original/raw rice weight. ・ For example, if the raw rice is 1kg, the finished amount of koji rice is 1.62-1.8 kg. (This is an estimated amount. The amount of finished koji rice depends on the soaking condition, steaming condition, and the condition of fermentation process). The color of the finished rice koji is reddish-brown and smells strange. Can I use it? There is a high possibility that other bacteria are mixed and increasing in the process of making it. Please don't use it. After you have sterilized all the equipment, please try increasing the amount of koji starter when making koji rice next time (about 3-4 times more) so it's easier to ferment. In addition, please be careful about temperature control during the fermentation process. Customer's Voice I drink amazake all year round, so I make my own koji at home. The improved choshiro fungus is safe because the sugar content of amazake can be stably increased. (Female, 60s) For the first time, I made koji from a koji starter. Thanks to Kawashima-ya's detailed recipe. Even as a beginner, I was able to make it without failure. I felt that mycelium was a little low, but I think it was a success because I made a sweet amazake. The next time I make it, I feel like I can do better than this time. (Female, 50s) The amazake on the market is too sweet, so I bought this koji starter. A delicious amazake with a refreshing sweetness and aroma of koji was made in my home. I'm satisfied.
