Score the surface of the drumsticks with a sharp knife in 3 or 4 places, to help the flavor penetrate, and set aside.
In a small bowl mix together honey, ginger, soy sauce, chili paste and vinegar.
Coat the drumsticks with the marinade and place on a greased baking dish. If you are not in a hurry you may want to put the drumsticks with the marinade in a plastic bag for at least 30 minutes to let the flavors combine better.
Place the drumsticks in the preheated oven, and after 30 minutes of baking start basting the drumsticks with reserved marinade, for few times while baking, until sticky, caramelized and nicely browned, for another 10 or 15 minutes more.
Remove, sprinkle chopped spring onion or chives on top and serve alongside a fresh salad.
