Onigirazu is a variation on a Japanese rice ball or onigiri. Onigiri is traditionally shaped like a ball or triangle, while onigirazu is shaped into a square or rectangle shape. It is essentially a hybrid rice ball sandwich.
Onigirazu should not erroneously be called a sushi sandwich. A sushi sandwich would use vinegared, seasoned rice. Onigirazu uses plain, white rice. The word "sushi," in culinary circles, is a reference to the type of rice used.

Place Rice on Dried Nori Seaweed
Continue to 2 of 9 below.
- Make sure your workspace is prepped to make onigirazu by laying a large piece of plastic wrap over a clean dry cutting board or another hard flat surface.
- Lay a large sheet (approximately 7 inches by 8 inches) of dried seaweed (nori) squarely on the plastic wrap.
- Spread about 1/2 cup steamed rice in the center of the dried seaweed in a diamond shape, with the tip of the diamond at the top of the sheet of seaweed. Make sure your rice paddle is moistened with water to help prevent rice from sticking.
- Optional: sprinkle dried roasted sesame seeds over the steamed rice for additional flavor.

Slice in Half (Optional)
Continue to 9 of 9 below.
- With the plastic wrap still intact, slice the onigirazu in half with a sharp knife. For best results use a ceramic knife. Rice can sometimes get sticky. To prevent the rice from sticking to the knife, moisten the knife with water.
