Ingredients
- 2 cups Japanese short-grain rice, rinsed until water runs clear
- 2 ¼ cups water (for cooking rice)
- 1 tsp salt
- 1 sheet nori (seaweed), cut into 6 strips

- 2 tbsp cooked kombu seaweed simmered in soy sauce and mirin
- 2 tbsp tuna mixed with Japanese mayo and a splash of soy sauce
- Water for wetting hands
- Additional salt for sprinkling
Instructions
- Cook the Rice: Combine rinsed rice and 2 ¼ cups water in a rice cooker or pot. Cook until tender and fluffy, about 20 minutes, then let it rest covered for 10 minutes to steam through evenly.
- Prepare Fillings: While rice cooks, prepare your chosen fillings.For salmon flakes, lightly flake cooked salmon and sprinkle with salt. For kombu,ensure it is soft and savory but not too salty.
- Season & Cool the rice: Transfer rice to a large bowl, gently fluff with a rice paddle or wooden spoon. Sprinkle salt evenly over the surface and fold softly to distribute without crushing grains. Let cool slightly until warm but easy to handle.
- Wet Your Hands: Dip hands in water lightly and sprinkle a pinch of salt on palms to season and prevent sticking.
- Shape the Rice Ball: Scoop about ½ cup of rice in your palm. Create a slight indentation with your thumb, placing about 1 tbsp filling inside. Carefully mold rice around the filling, shaping it into a tight triangle or oval. Apply gentle pressure while keeping the texture intact.
- Add Nori: Wrap a strip of nori around the base or lay it over the onigiri just before serving. This adds a contrasting crispness and eases handling.
- repeat: Continue making remaining onigiri, adjusting salt and filling quantity as preferred.
Tips for Success
- Rice Texture: Use short-grain rice-its natural stickiness is essential. Avoid overcooked or dry rice,which won’t hold shape.
- Shaping Technique: Do not over-press. Aim for a firm but light hold, allowing the onigiri to retain a tender bite.
- Filling Balance: Less is more.Overstuffing can cause onigiri to burst or become soggy quickly.
- Make-Ahead: Wrap onigiri individually in plastic wrap or reusable beeswax sheets for freshness; consume within 24 hours for ideal texture.
- Variations: Try adding toasted sesame seeds or furikake spices on the exterior for extra flavor.
- For Gluten-Free Option: Use gluten-free soy sauce for kombu or tuna fillings.
