Onigiri (Rice Balls)
Why this recipe works
- Reliable shaping: Warm, lightly seasoned rice is shaped with damp hands so it holds together without becoming heavy or crushed.
- Good texture contrast: Soft rice, flaky salmon and crisp nori give each rice ball a balanced bite when the seaweed is added at the last moment.
- Easy to pack: Onigiri can be eaten warm or at room temperature, making them practical for snacks, lunchboxes and simple packed meals.

Timing notes
- Let the rice steam: Keeping the rice covered after cooking helps the grains finish steaming evenly and improves the final texture.
- Wrap just before eating: Add the nori at the last moment so it stays crisp rather than softening against the rice.
- If chilled: Bring refrigerated onigiri back towards room temperature before serving for a softer, more pleasant rice texture.
Texture tips
- Shape firmly, not forcefully: Press the rice enough to hold its shape, but avoid compressing it so much that the grains lose their definition.
- Keep the nori separate: For packed onigiri, store the nori apart from the rice balls and wrap only when ready to eat.
- Cook the salmon gently: Stop cooking once the salmon is opaque and flakes easily to keep the filling moist rather than dry.
Ingredient notes
- Use short-grain rice: Sushi rice or Japanese short-grain rice has the stickiness needed to form neat, stable onigiri.
- Rinse the rice well: Rinsing until the water is almost clear removes excess surface starch and helps the cooked grains feel glossy rather than gluey.
- Be careful with vinegar swaps: White wine vinegar can replace rice vinegar, but it tastes sharper, so the seasoning may need a more cautious hand.
Ingredient swaps
- Use canned salmon: Drained canned salmon makes a quicker filling; flake it well before shaping so it sits neatly inside the rice.
- Try another mild vinegar: If rice vinegar is unavailable, a mild white wine vinegar can work, though the flavour will be slightly more assertive.

Ingredients
Instructions
- Rinse the sushi rice in a bowl of cold water, swishing gently, then drain; repeat until the water runs almost clear. Tip into a saucepan and add 180 ml water. Bring to the boil, cover, then cook on the lowest heat for 12 minutes.
- Turn off the heat and leave the rice, still covered, for 10 minutes to steam. Meanwhile, cook the salmon in a dry nonstick pan over medium heat for 3 to 4 minutes per side, until opaque and just cooked through. Flake the salmon into small pieces and season it with a pinch of the fine sea salt.
- Transfer the hot rice to a mixing bowl and sprinkle over the rice vinegar and the remaining fine sea salt. Fold gently with a spatula until the rice is glossy and evenly seasoned, taking care not to mash the grains. Let the rice cool for 5 minutes so it is warm but comfortable to handle.
- Cut the nori sheet into 2 rectangles for wrapping. With damp hands, divide the rice into 2 portions and flatten one portion in your palm. Place half the salmon in the centre, then bring the rice up and around the filling and press into a firm triangle or ball; repeat with the remaining rice and salmon.
- Wrap each onigiri with a strip of nori just before eating so it stays crisp. Serve warm or at room temperature. If packing for later, keep the nori separate and wrap at the last moment.
Recipe notes
Tips
- Keep a small bowl of water nearby to dampen your hands; it stops the rice sticking and helps you shape the onigiri firmly.
- Press the rice firmly enough that it holds together, but avoid crushing the grains, which can make the texture heavy.
- If serving to anyone who is pregnant, elderly, or immunocompromised, make sure the salmon is cooked through and the rice is cooled and stored safely.
Substitutions
- Replace the salmon fillet with canned salmon for a quicker filling; drain well and flake before shaping.
- Replace rice vinegar with white wine vinegar for a slightly sharper seasoning.
Storage
- Refrigerate up to 1 days
- Onigiri are best eaten the day they are made. If refrigerating, store the rice balls and nori separately in an airtight container; bring the rice balls back to room temperature before eating and wrap with nori just before serving.
