Preheat your oven to 425°F and line a large baking sheet with parchment paper.
Pat the chicken wing drumettes thoroughly dry with paper towels to ensure the skin becomes extra crispy.
In a large mixing bowl, toss the drumettes with arrowroot starch, sea salt, black pepper, and garlic powder until each piece is evenly coated.
Arrange the wings in a single layer on the prepared baking sheet and bake for 35-40 minutes, flipping halfway through for even browning.
While the wings are baking, combine the honey, coconut aminos, rice vinegar, toasted sesame oil, and grated fresh ginger in a small saucepan over medium-low heat.
Simmer the sauce for 3-5 minutes until it thickens slightly into a glossy glaze.
Transfer the hot, crispy wings to a clean bowl and pour the warm glaze over them, tossing gently to coat.
Garnish with sesame seeds and thinly sliced green onions before serving immediately.
