Make the Yakitori Sauce: In a small saucepan, combine soy sauce, mirin, sugar, and sake. Simmer over medium heat for 5–7 minutes until slightly thickened. Set aside.
Prepare the Meatball Mixture: In a bowl, mix ground chicken, green onions, egg, panko, soy sauce, and grated ginger. Stir until well combined.
Shape the Meatballs: With damp hands, form small meatballs or oval shapes (about 16 pieces).
Cook the Meatballs: Heat a skillet over medium heat with a little oil. Sear meatballs for 3–4 minutes per side until golden and cooked through.
Glaze with Yakitori Sauce: Pour yakitori sauce over the meatballs and simmer for 2–3 minutes, turning to coat evenly in the thick glaze.
Serve: Serve hot with steamed rice or skewer them for a traditional touch.
Notes
Cooking tips:
Use chicken thighs for extra juiciness, or a mix of thigh and breast.
Wet hands help prevent sticking when shaping meatballs.
Don’t overcook the glaze—it thickens quickly as it cools.
