• Cooked salmon, flaked

Essential Tools and Equipment

• Fine-mesh strainer
• Small bowl of water
• Clean kitchen towel

Step-by-step process (detailed)

1. Rinse the rice

Place rice in a bowl and rinse under cold water, gently swirling and draining. Repeat 3–4 times until the water runs mostly clear. This removes excess surface starch and ensures fluffy—not gummy—rice.

2. Cook the rice

Add rinsed rice and measured water to a rice cooker and cook on the white rice setting. If using a saucepan, bring to a gentle boil, cover, reduce to low, and cook for 15 minutes. Remove from heat and let steam, covered, for 10 minutes. The rice should be tender, glossy, and slightly sticky.

3. Prepare fillings

While the rice cooks, prepare fillings and keep them dry and compact. Large or wet fillings can cause onigiri to fall apart. Chop or flake fillings finely so they sit neatly inside the rice.

4. Season your hands

Mix salt with a bowl of water. Lightly dip your hands, then shake off excess. Your hands should be damp, not wet. This prevents sticking and lightly seasons the exterior.

5. Portion the rice

Scoop about ½ cup of warm rice into your palm. Warm rice shapes more easily and holds together better than cold rice.

6. Add filling

Make a small indentation in the center of the rice. Add 1–2 teaspoons of filling. Avoid overfilling—this is the most common mistake.

7. Shape gently

Fold rice over the filling. Using both palms, gently shape into a triangle or round using light pressure. Rotate and shape 2–3 times only. The goal is airy and tender, not compacted.

8. Wrap with nori

Wrap nori around the onigiri just before eating for a crisp texture, or wrap partially if packing to-go. For lunch boxes, keep nori separate until serving if possible.

Mistakes to avoid

• Using long-grain rice — won’t hold shape
• Pressing too firmly — dense, tough texture
• Overfilling — causes cracking
• Shaping cold rice — poor cohesion
• Wet fillings — soggy rice
