Onigiri Option

Onigiri can also be made in plastic wrap. They will turn out round not triangular.

Cut small pieces of plastic wrap.
Place rice in the center of the wrap.
Wrap the rice pulling the ends of the plastic together.
Twist ends. A piece of ribbon is sometimes used to tie them together.
Cup the wrapped rice to make a ball.

These are easier to eat because the plastic is tied together. Onigiri are made this way here in Japan. I'll try to take a picture of this kind of onigiri.

Check the original posting. I added more info. about onigiri. You may have missed it.

Note: Whenever you clump rice together it is possible it could turn into a choking hazard. Onigiri are not a choking hazard. However, if you're doing it for the first time and you're crunching it all together you may get a gooey mess. You should be able to see each individual grain of rice. Watch out.
