About this dish

The signal that these rice balls are right is the faint crackle of nori meeting warm rice, tightening from limp to crisp within a minute. Press the grains while they still steam your palms, since cold rice refuses to bind and the triangles split at the seam. Diced sausage renders amber fat into the pan and the corn answers with milky sweetness that cuts the salt. Wrap the seaweed last or it softens; that dry snap against faintly vinegary rice is why they survive a lunchbox.

Method

6 steps · tick each one off as you finish it.

  1. Rinse and steam the rice

    Rinse 360 g rice in cold water for 30 seconds, drain, and repeat twice until the water runs clear. Add 430 ml water and steam in a rice cooker for 20 minutes, then rest 10 minutes off the heat until the lid stops hissing.

  2. Season the hot rice

    Tip the hot rice into a wide bowl and, off the heat, sprinkle over 1 tbsp rice vinegar, 1 tsp salt and 1 tsp sesame seeds. Fold for 1 minute with a damp spatula until the grains look glossy and the vinegar smell fades.

  3. Brown the sausage

    Heat 2 tsp oil in a skillet over medium-high heat for 1 minute until it shimmers. Add 160 g diced sausage and fry 4 minutes, stirring twice, until the edges brown and the rendered fat turns the pan glossy and amber.

  4. Glaze the corn

    Stir 120 g corn into the skillet over medium heat and cook 2 minutes until the kernels brighten and pop. Add 1 tsp soy sauce, toss 30 seconds until the pan smells caramelised, then scrape everything onto a plate to cool 5 minutes.

  5. Shape the triangles

    Wet your palms, flatten 90 g rice and spoon 25 g cooled filling into the centre, then press 20 seconds off the heat into a triangle until the seams close and the shape holds when you turn it over. Make 8 balls.

  6. Wrap with seaweed

    Lay one 8 g nori strip shiny-side down and wrap it around each triangle, pressing 10 seconds to seal. Rest the balls 5 minutes off the heat until the seaweed turns crisp and crackles when tapped, then pack them seam-side down.

Tips that matter

  • If the rice slips apart, your hands are too dry; rewet them and press again, since a film of water stops the grains sticking to your skin instead of each other.
  • Wrap the nori no more than 30 minutes before eating; the salt in the seaweed draws moisture from the rice and the sheet turns leathery.

Easy variations

  • Swap the sausage for 150 g flaked cooked salmon and add 1 tsp sesame seeds to the rice.
  • For a vegetarian batch, use 120 g finely diced shiitake fried in 2 tsp oil in place of the sausage.

Questions that come up

Why do my rice balls fall apart when I unwrap them?

The rice was shaped while cold or pressed too loosely. Shape it while still warm, squeeze firmly for 20 seconds, and let the triangles firm up 5 minutes before wrapping.

Can I make these the night before?

Yes, but keep rice and nori separate. Store the shaped triangles wrapped in cling film in the fridge for up to 24 hours and wrap with seaweed just before packing.
