Prepare the rice

• Place the warm cooked rice in a bowl.
• Wet your hands and season the rice lightly so it holds together.

Shape the onigiri

• Take a portion of rice and flatten it in your palm.
• Place the mozzarella in the center and cover with more rice.
• Press into a triangle or rounded shape, sealing the cheese inside.

Make the glaze

• Mix the soy sauce, mirin and sesame oil in a small bowl.

Air fry the onigiri

• Brush the onigiri with the glaze.
• Air fry at 190 °C, brushing with more glaze and turning halfway through, until golden and crisp.

Finish and serve

• Brush the hot onigiri with the remaining glaze.
• Sprinkle with toasted sesame seeds and serve warm while the cheese is melted.
