Notes
*1 If you don't have a rice cooker, please refer to the post "how to cook rice without a rice cooker" *2 You can replace with any rice seasonings. *3 It does not have to be a triangle shape. You can shape them any way you like. Tip 1: Shape the cooked rice while the rice is still warm. It will be a little difficult to shape when the rice has cooled. Tip 2: Shape firmly to avoid the rice balls falling apart while they are grilled. *4 Be careful not to burn the rice balls once you brush with miso sauce because miso sauce contains sugar so could be easily burnt.
