To prepare, start by cooking the rice and spreading the furikake seasoning onto a plate.
Once the rice is done cooking, cut the nori sheets into three evenly sized strips. Then cut the strips in half and place aside until needed. Be sure to use high quality, fresh nori so it will be nice and crispy.
When you are ready to assemble the onigiri, wet your hands and rub a little bit of salt on them prior to handling the rice. This helps to season the rice and keep it from sticking to your hands. Then form a half a cup of rice into a triangle shape by cupping your hands and gently pressing the rice with your palm and fingers (see video for more detail). Most beginners tend to press too hard when shaping the rice. Instead, you want to gently use your hands to form the rice into a triangle shape.
Dip the edges of the rice triangle onto the plate with furikake seasoning, coating all sides.
Next, wrap a half strip of the nori around the bottom center of the onigiri.
Serve and enjoy!
