While okaka provides the signature flavor, you can substitute with other ingredients like sesame oil, furikake seasoning, or even finely chopped seaweed for a different taste profile.

Gently but firmly shape the onigiri, ensuring the rice is slightly moist but not overly wet. Wetting your hands slightly before shaping can help.
