Wash and drain rice 3-4 times until the water runs less milky (it’s ok if it’s not completely clear). You can wash in the rice cooker bowl or a large mesh strainer
Add washed and drained rice to rice cooker
Add soy sauce, mirin, sake, dashi powder, sugar to rice
Add water. It should hit the 2 line on the rice cooker, if you have the indications
Mix rice so all the ingredients are combined together
Add in sliced onion and sliced beef respectively
Season beef with a pinch of salt
Close the lid and set rice cooker to the usual cooking time for rice. My rice cooker cooks rice in 55 minutes
Once the cooking time is done, mix the rice in a cutting motion to distribute the toppings evenly
Place cooked rice in a bowl and add preferred toppings
Or make it into onigiri or rice balls (I am using an onigiri mold)
You can take the onigiri as a snack on the go and enjoy!
