How to Make Fermented Brown Rice
There are four steps to make Koso Genmai:
Step 1: Wash brown rice and red beans
Step 2: Add salt and water and mix
Step 3: Immersion and rice cooking
Step 4: Warming and Fermentation
1. Wash brown rice and red beans
First, put the brown rice and azuki beans in the bowl, wash it slowly.
Clean the dirt and dust from the brown rice and azuki beans.
As brown rice absorbs water just like white rice, let's drain the water first.
Wash and drain the water, wash it again and drain the water, repeat for 3 or 4 times.
2. Add salt and water and mix it together
Add brown rice and red bean, water, salt and mix it together.
Please adjust the amount of water according to the capacity of the rice cooker.
3. Submersion and rice cooking
If you use a regular rice cooker, leave the brown rice in water for about 1 hour before cooking.
After that, we will cook the rice. If the rice cooker has brown rice cooking mode, please use its function.
If the rice cooker has germinated brown rice function, the process from germination to cooking rice can be done only by button operation.
4. Thermal Insulation and Fermentation
When the brown rice cooked, heat it with rice cooker for two until four days.
While keeping it warm inside the rice cooker, stir the brown rice once a day.
While keeping it warm inside the rice cooker, stir the brown rice once a day. When stirring, use a rice paddle to stir it thoroughly once a day to prevent the surface from drying out.
If you concerned, you can prevent the rice from drying by using a wrap or wet cloth on the surface. It will be ready to serve after two until four days of cooking.
Warming · Fermentation Day 1
The rice became slightly darker than normal brown rice.
Warming · Fermentation Day 2
The brown rice turned slightly purple.
The brown rice tastes richer compared to the first day.
Warming · Fermentation Day 3
As the fermentation progressing, the brown rice colour become darker.
The texture will get puffier.
Warming · Fermentation Day 4
Koso Genmai is ready to be consumed.
The umami flavour and its puffy texture are appealing.
Koso Genmai can be consumed for about 7 days after it's done cooked.
With four steps above, the making of delicious and puffy Koso Genmai is completed.
By fermenting it, the bad part of brown rice will vanish and be replaced with its delicious taste.
By fermenting and keep the rice brown warm, it will produce melanoidin (brown coloured component in food). Due to the antibacterial action from the melanoidin, brown rice becomes Koso Genmai without corrosion or decay.
Furthermore, by fermenting the rice brown, it is said that the nutrient called GABA (gamma-aminobutyric acid) will increase even higher than the normal brown rice.
It should be noted that in this video, we use rice cooker with germinated brown rice function.
It is recommended to use the rice cooker with such function because you can eat Koso Genmai simply by button operation.
