1. Soak the bamboo skewers in water for 30 minutes.

Yakitori Sauce (Tare)

1. In a small saucepan, combine the mirin, soy sauce, sake, water, brown sugar, and the green part of 1 spring onion. Bring to a boil over high heat. Once boiling, reduce the heat to low and simmer, uncovered, until the liquid is reduced by half, about 30 minutes.
2. Remove from the heat and let the sauce cool to room temperature. Reserve ⅓ of the sauce in a small bowl for the final coating.

Yakitori

1. Cut the white and light green parts of the scallions into 2.5 cm – 1-inch pieces.
2. Cut the chicken into 2.5 cm – 1-inch cubes.

3. Thread the chicken onto the skewers at a 45-degree angle.

4. Alternate each piece of chicken with a piece of spring onion.
5. Grease the grate of the broiler or wire rack (or an oven-safe cooling rack) to prevent sticking. Place the skewers on top.
6. Set the broiler to high and wait until the heating elements are hot. Broil for 6 minutes.
7. After 6 minutes, brush the sauce over the chicken on both sides and continue to broil for 3–4 minutes, until the chicken is cooked through and the sauce has caramelised.
8. Transfer the skewers to a serving plate and brush the chicken with the reserved sauce using a clean brush.*
9. Serve warm.
