Preheat your oven to 375 degrees f. and place a rack over a large roasting pan.
Pour about 1 cup of water into the roasting pan.
Alternatively, you could heat up your outdoor grill to 375 degrees, spray the grates and BBQ these using the same instructions below, and watching them very closely throughout the process.
In a small bowl whisk all glaze ingredients together really well. Set aside.
Pat your drumsticks dry with paper towels and sprinkle with sea salt, pepper and baking powder, then toss well to coat.
Arrange the chicken onto your prepared roasting tray/rack (suspended above the water on grates as shown) then roast for about 35 minutes, flipping them halfway through.
You'll know when they're done, as juices run clear and the skin is golden and crispy.
Remove from the oven and brush them with your glaze, then place back into the heated oven for just 1-2 minutes.
Repeat this process several times for the next 5-6 minutes so that they get 3 layers of this delicious glaze.
Sprinkle the drumsticks with sesame seeds and green onions and serve with any remaining untouched sauce (sauce shouldn't touch raw chicken)
