Onigiri de salmón y alga nori

Onigiri are a staple of Japanese street food, known for their triangular shape and savory fillings. This salmon and nori seaweed version combines the soft texture of rice with the rich flavor of smoked fish, creating a portable and umami-packed bite. They are perfect for taking anywhere or enjoying at home.

Ingredients

How many are you cooking for?

Original recipe for 4 servings

  • 200 g short-grain Japanese rice
  • 240 ml filtered water
  • 150 g fresh salmon cubes
  • 1 tbsp soy sauce
  • 1 tbsp rice vinegar
  • 4 strips dry nori seaweed
  • 1 tbsp vegetable oil

Step by step

Follow the timeline: technique icon, time and temperature when relevant.

  1. Step 1 Prep 15 min

    Rinse short-grain rice three times until the water runs clear to remove excess starch and prevent it from becoming too sticky. Cook with a 1:1 water-to-rice ratio over high heat until boiling, then reduce to medium and cover for 12 minutes. Controlled steam cooks the grains evenly without breaking them. Tip: use a heavy-bottomed pot to distribute heat evenly.

  2. Step 2 Pan 4 min

    While the rice rests, cut the salmon into small cubes and sear them in a non-stick pan over medium heat with one tablespoon of soy sauce for 4 minutes. The soy sauce adds umami and helps seal the fish proteins. Remove from heat and shred with a wooden spoon. Tip: add a few drops of lemon juice to cut the fat and highlight the salmon flavor.

  3. Step 3 Prep 1 min

    Prepare a bowl with warm water mixed with one tablespoon of rice vinegar to wet your hands, creating a barrier that prevents the rice from sticking to your skin. Place three tablespoons of slightly warm rice in your palm and smooth the edges. Tip: the rice should be warm, not hot, so it holds its structure when pressed.

  4. Step 4 Assemble 3 min

    Make a hole in the center of the rice and fill it with a generous spoonful of the crumbled salmon, ensuring a two-centimeter margin on the edges to seal well. Press the sides with your thumb and middle finger while rotating your hand to form the classic triangle. Tip: apply pressure only to the base and tips to avoid deforming the center.

  5. Step 5 Assemble 1 min

    Wrap each onigiri with a 3 cm wide strip of dry nori seaweed, leaving the top uncovered so the rice breathes and maintains its crisp texture. The seaweed will stick better if you lightly moisten it with a brush before placing it. Tip: store unused seaweed in a zip bag to prevent it from softening due to ambient humidity.

  6. Step 6 Rest 5 min

    Place the onigiri on a tray lined with parchment paper and let them rest at room temperature for five minutes so the rice settles and the flavors integrate. Serve immediately with green tea or ponzu sauce. Tip: if you prepare them ahead, wrap them individually in plastic wrap to keep them fresh until eating time.

Storage

Store onigiri without the seaweed in an airtight container in the fridge for up to 24 hours; add the nori just before eating to keep it crisp. Do not freeze due to the soft texture of the rice.

Chef tips

  • Always rinse the rice until the water runs clear; this removes excess starch and prevents the onigiri from falling apart when pressed.
  • Keep your hands wet by changing the water every two onigiri to prevent starch from sticking to your fingers and ruining the shape.
  • Use a triangular silicone mold if you struggle to shape them by hand; press the rice firmly but do not compact it too much to preserve the airiness.
