For the Rice Balls
- 300 g cooked leftover rice slightly warmed
- 5 ml cooking oil
- 30 g carrot finely diced
- 50 g luncheon meat Spam, finely diced
- 30 g corn kernels cooked
- 30 g shredded seaweed seaweed flakes
- 15 g salad dressing mayonnaise
- 4 slices cheese
- 4 rectangular roasted seaweed sheets nori
For the Teriyaki Glaze
- 15 ml 1 tbsp soy sauce
- 15 ml 1 tbsp oyster sauce
- 15 g 1 tbsp honey (or to taste)
Mix the Rice
Place the leftover rice in a large bowl and drizzle in the cooking oil. Add the diced carrots, luncheon meat, corn kernels, and seaweed flakes.
Squeeze in the mayonnaise and mix thoroughly until every grain of rice is coated and the ingredients are evenly combined.
Shape and Fill
Take about 70g of the rice mixture and flatten it into a disc in your palm.
Place one slice of cheese in the center (you can fold it to fit). Top with another small portion of rice, then gently cup and press your hands to form a compact triangle (or round ball), ensuring the cheese is completely sealed inside with no gaps.
Wrap a sheet of nori around the bottom of the rice ball. Repeat to make 4 rice balls.
Make the Glaze and Cook
In a small bowl, whisk together the soy sauce, oyster sauce, and honey until smooth.
Air Fryer Method: Place the rice balls in the air fryer basket. Brush the top and sides generously with the teriyaki glaze. Cook at 180°C (350°F) for 7 minutes. Carefully flip the rice balls, brush the other side with more glaze, and cook for another 7 minutes, or until the surface is caramelized and crispy.
Stovetop Method: Heat a non-stick pan over medium heat with a thin layer of oil. Place the rice balls in the pan and cook for 3-4 minutes until the bottom is golden. Flip, brush the cooked top with glaze, and cook another 3-4 minutes. Flip again, brush the other side, and cook until crispy and glazed on all sides.
