Use white rice and omit the optional ingredients if you are having digestive problems, experiencing diarrhea, or on a low-fiber and/or bland diet.
Okayu makes for a delicious savory change from oatmeal for breakfast. Here’s a way to make it the night before with uncooked rice:
1. Wash ½ cup of rice and put it into a pan with 3-4 times its volume of water. Bring it to a boil, cover tightly, then turn off the heat and leave overnight.
2. By the morning, the rice will have soaked up nearly all of the water. Add more water to taste, depending on how soupy you prefer the oyaku. Bring to a boil and simmer for 15-20 minutes stirring from time to time. If it gets too thick, add a little boiling water. Serve with recommended toppings.
