Hi, I've been attempting to make onigiri and yaki onigiri with Nishiki brand medium grain polished rice for sushi. I cook it in a rice cooker using 1 part rice to 1 1/2 parts water and a little salt. I can form the onigiri balls alright and they hold together when I fry them till they are a light brown but they fall apart when I try to pick them up.
Do I need to compact the rice more? Am I using the wrong ratio of rice to water? I can't imagine being able to cook these on the grill as fragile as they are now.
Also, can I use the medium grain brown rice for onigiri?
