Onigiri (Japanese Rice Balls)

Tips & Variations

Variations

  • Yaki onigiri: Brush with soy and grill or pan-fry for a crisp crust.
  • Tuna mayo / mentaiko / salmon / umeboshi: Swap the filling freely.
  • Korean jumeokbap: Mix rice with sesame oil, salt, nori flakes, and tiny anchovies, then roll into balls.
  • Onigirazu: Wrap rice and filling flat in nori for a 'rice sandwich.'

Tips

  • Shape the rice while fresh and warm so it holds (cold rice crumbles).
  • Wet hands with salted water so it won't stick and gets seasoned.
  • Don't squeeze hard — shape gently so it stays fluffy once cooled.
  • Add the nori just before eating for crispness; pack it separately for lunch.
  • Keep the filling small and centered.
