Ingredients

Method

Directions

  1. 1

    Prepare the sushi rice

    Rinse the sushi rice under cold water until the water runs clear. Combine the rinsed rice and water in a rice cooker and cook according to the manufacturer's instructions.

  2. 2

    Prepare the tuna filling

    In a bowl, mix the drained tuna with Kewpie mayonnaise, soy sauce, and salt until well combined.

  3. 3

    Shape the onigiri

    Once the rice is cooked and slightly cooled, wet your hands with water and take a handful of rice. Flatten it into a triangle shape and place a spoonful of the tuna mixture in the center. Mold the rice around the filling to encase it completely, and shape it into a triangle.

  4. 4

    Wrap with nori

    Cut the nori sheet into strips and wrap a piece around each onigiri for added flavor and presentation. Optionally, sprinkle sesame seeds on top.

  5. 5

    Serve

    Enjoy your Tuna Mayonnaise Onigiri immediately or wrap in plastic wrap for later.
