- 1½ tablespoons Japanese mayonnaise
- 1½ teaspoons soy sauce
- ½ teaspoon sesame oil
- ⅛ teaspoon rice vinegar
- ¾ teaspoon sriracha (optional)
For the Rice Balls
- 1½ cups freshly cooked Japanese short-grain rice
- Salt, for seasoning
- 3 nori sheets, cut into 4 x 1½-inch strips

Instructions
Step 1: Prepare the Salmon Filling
In a medium bowl, combine the flaked salmon, Japanese mayonnaise, soy sauce, sesame oil, rice vinegar, and sriracha if using.
Mix until the filling is creamy and evenly combined.
Set aside while preparing the rice.
Step 2: Prepare the Rice
Cook Japanese short-grain rice according to the package instructions.
Allow the rice to cool slightly until it’s warm enough to handle but still sticky.
Lightly wet your hands or the onigiri mold with water and sprinkle with a small pinch of salt to prevent sticking.
Step 3: Fill the Onigiri Mold
Add a thin layer of rice to the bottom of the mold.
Press gently to create an even base.
Place about 1½ tablespoons of the salmon mixture into the center.
Cover with additional rice until the filling is completely enclosed.
Press firmly with the mold lid until the rice is tightly packed.
Carefully release the shaped onigiri from the mold.
Step 4: Wrap with Nori
Wrap each rice ball with a strip of nori.
If desired, roll the exposed sides in furikake seasoning for extra flavor and texture.
Repeat with the remaining rice and salmon filling.
Serve immediately while the rice is still soft.

- Use freshly cooked short-grain Japanese rice for the best texture.

Frequently Asked Questions
What kind of rice is best for onigiri?
Japanese short-grain rice is essential because its sticky texture helps the rice balls hold their shape.
Can I use fresh salmon instead of canned salmon?
Absolutely. Flake cooked baked, grilled, or pan-seared salmon before mixing it with the seasonings.
Can I make onigiri without a mold?
Yes. Wet your hands with water, sprinkle them lightly with salt, and shape the rice into triangles by hand.
How long does homemade onigiri last?
For the best texture, enjoy within 24 hours. Refrigeration can make the rice firm, so allow it to return to room temperature before eating.
Can I freeze salmon onigiri?
Yes. Wrap each rice ball tightly in plastic wrap and freeze for up to one month. Add fresh nori after reheating.
What other fillings can I use?
Popular fillings include tuna mayonnaise, grilled salmon, teriyaki chicken, pickled plum (umeboshi), spicy tuna, shrimp, and seasoned vegetables.
