Preheat oven to 425°F. (400 F for Fan Forced Oven)
Line a baking tray with a double layer of foil. Then top with parchment paper.
In a big bowl, mix all the sauce ingredients. Toss wings into the sauce and coat it well.
Shake off excess marinade, arrange wings in a single layer, leaving a little space in between. (Use two trays, if it is too crowded in on pan)
Bake for 20 minutes. Take the baking tray out, bast the wings with marinade. Bake again for 25-30 minutes.
Towards the end of the baking, Cook the remaining chicken marinade in a small pan. Once it comes to a boil, reduce the heat and cook for 1 more minute until the sauce has thickened.
Take the wings from the oven. Brush the thickened sauce on the wings.
Sprinkle some sesame seeds and green onion and serve.
