Description

Japanese tuna onigiri brings oceanic flavors wrapped in perfectly seasoned rice. Compact hand-held parcels deliver quick comfort with minimal preparation, letting home cooks savor authentic Japanese street cuisine in mere moments.


Ingredients

Scale

Main Ingredients:

  • 2 cups cooked short grain rice
  • 5.29 ounces (150 grams) canned tuna, drained
  • 0.5 sheet nori, cut into 2 strips

Seasoning Ingredients:

  • 0.5 teaspoon salt
  • 1 teaspoon sesame oil

Binding Ingredient:

  • 2 tablespoons mayonnaise (Kewpie mayo)

Instructions

  1. Prepare a clean work surface and lay out a sheet of plastic wrap for easy rice shaping and handling.
  2. Season warm rice with sesame oil and salt, mixing thoroughly to ensure even distribution of flavors.
  3. Drain canned tuna and combine with mayonnaise, creating a creamy and smooth filling mixture.
  4. Divide the seasoned rice into equal portions, forming gentle circular shapes approximately half an inch thick on the plastic wrap.
  5. Place a portion of tuna mixture directly in the center of each rice circle, creating a small indentation.
  6. Carefully gather the plastic wrap’s edges, gently twisting and molding the rice around the tuna filling to create a compact, triangular or round onigiri shape.
  7. Slice nori seaweed into thin strips, ensuring each onigiri receives a decorative and flavorful wrap.
  8. Delicately unwrap the plastic and adjust the onigiri’s shape, smoothing any uneven surfaces for a refined presentation.
  9. Optional: Lightly toast the nori strip before wrapping around the rice ball to enhance its crisp texture and aromatic profile.
  10. Serve immediately while the rice remains warm and the texture is at its peak, perfect for a quick and satisfying Japanese-inspired snack.

Notes

  • Prep rice while warm for better binding and easier shaping, ensuring a smooth, cohesive texture that holds together perfectly.
  • Use fresh canned tuna drained thoroughly to prevent excess moisture from making the onigiri soggy or falling apart.
  • Plastic wrap is a game-changer for creating uniform, professional-looking rice balls without sticky hands.
  • Sesame oil adds a subtle nutty flavor that elevates the traditional Japanese rice ball from simple to spectacular.
  • Nori strips not only provide an authentic touch but also create a convenient handle for eating, keeping hands clean and adding a delightful seaweed crunch.
  • Portion control matters – aim for consistent size to ensure even cooking and a beautiful presentation that looks intentional and skillful.
