Note this recipe uses RICE cups for the beans and rice. Not full cups.
A rice cooker cup measurement is approx. ¾ cup.
In a medium saucepan, cover the adzuki beans with water and bring to the boil over high heat. Drain.
70 g adzuki beans
Add 2 cups of water to the adzuki beans and bring back to the boil. Then reduce to a simmer over medium heat and cook for 20 minutes. Turn off the heat and allow to cool (around 30 minutes - 1 hour) in the remaining liquid (this will be used to colour and cook with the rice).
2 cups water
Place the glutinous rice in the rice cooker bowl. Wash and drain with water until the water runs clear (around 2-3 times).
280 g glutinous rice
Pour in the cooled adzuki beans and liquid over the rice, then fill up to the 2 1/2 cup point in your rice cooker with water.
Cook according to your rice cooker instructions, then serve hot or cold with a garnish of gomashio.
