Equipment

  • Plastic wrap optional

Ingredients
 
 

For tuna mayo filling

  • 3 ounces canned tuna drained
  • 2 tablespoons mayonnaise
  • 1 teaspoon sesame oil
  • 2 pinches salt or more

For rice balls

  • 3 cups cooked Japanese rice
  • 4 pinches salt
  • 1 sheet full size nori split into 4 strips

Instructions
 

  • In a small bowl, combine the tuna, mayonnaise, sesame oil and salt together. Mix well.
  • Place a piece of plastic wrap on a flat surface. Sprinkle a pinch of salt over the plastic wrap, then spread ¼ of the rice.
  • Place ¼ of the tuna mix in the middle of rice. Meet the edges of the plastic wrap together to form a rice ball, wrapping in the tuna. Make it into a triangular shape.
  • Remove the plastic wrap. Wrap the rice ball with nori. Repeat to make 3 more rice balls.

Notes

If you are shaping the rice balls without using plastic wrap, wet your hands to prevent the rice from sticking, and rub a pinch of salt in your hands to add an additional flavor to rice.
