Making amasake in a Ohsawa Pot within a Instant Pot

 This is the easiest way to' r ' make amasake that I have found,

You can use short medium or long grain rice, sweet rice or whole oat groats, preferably organic

You may be able to use millet, barley, or corn but probably not wheat or buckwheat and probably not quinoa, teff, amaranth or sorghum.

I rinse  1 or 2 cups rice 3 times and soak it 2 3/4 cups cups of (purified, spring, or artesian well) water per cup of rice for  at least 3 hours, usually 8 but sometimes as long as 24 hours.

The soaked rice and soaking water I add to a large Ohsawa Pot (especially if I have 2 cups of rice and 5 1/2 cups of water) add a pinch of sea salt for each cup of rice cover them and place it in the Instant Pot and pressure cook it for 45 minutes,

Afterwards I let the hot wet air escape from the Instant Pot before opening it and using a good pot holder I lift the OP lid and place it safely aside and check the cooked rice temperature with a cooking thermometer.

One wants the fermenting temperature to hover between 120 and 135 degrees so I add one cup of amasake koji for every cup of precooked rice mixing it in the rice thoroughly and check the temperature.

It it is too hot in the beginning I stir the rices to release extra heat before adding koji.

At about 150 degrees one can add cold koji and some water to get it to the right temperature making sure that the water just barely cover the rice the cover with the OP lid and then the Instant Pot lid and set the yogurt setting for at leasrt 5 hours and if away from the kitchen a timer on your smartphone is useful too,

After the rice has fermented sufficiently you release the hot wet stem then open hot pots and check the rice for sweetness.

If it is sweet enough then one can boil the amasake concentrate in the Instant Pot or on the stove for 10 minutes constantly stirring to pasteurize it and then add the concentrate to half gallon and quart wide mouth ball jars with silicone nipple pickle pipes attached and when sufficiently cooled add the covered jars to the refrigerator.

It keeps cold for at least a week!
