Steam the rice in a rice cooker or cooking pot for 8 minutes, drain and let it cool off
Meanwhile, cut the nori sheet into 8 – 9 strips, and then put around ½ cup of steamed rice in a rice bowl
Make sure that you wet your hands using water to prevent the rice from sticking
Rub your hands with some salt
Now, place the steamed rice on your hand—and make sure that it is thick and dense
You can now put your fillings—like grilled salmon or umeboshi on the rice and then push the fillings into the rice a bit
Next, hold the rice between your palms
Press it lightly using both palms to form a round, cylinder, or triangle shape, and then roll the rice ball with your hands, pressing it lightly
Using a strip or two of nori, wrap the rice ball or even sprinkle some sesame seeds on them
Serve
And of course, if you like the smiley faces for kids, or childlike dinner guests :) cut some of the nori into eyes and a smiling mouth for the triangle
