Preheat oven to 400°F and line a large baking sheet with parchment paper.
Pat the chicken wings completely dry with paper towels to ensure they become extra crispy during baking.
In a large bowl, toss the wings with arrowroot starch, sea salt, and black pepper until evenly coated.
Arrange the wings in a single layer on the baking sheet and bake for 35-40 minutes, flipping halfway through.
While the wings bake, combine honey, tamari, minced garlic, grated ginger, vinegar, and sesame oil in a small saucepan.
Simmer the sauce over medium-low heat for 5-7 minutes until it reduces into a thick, glossy glaze.
Remove the wings from the oven, toss them in the warm glaze until fully coated, and garnish with sesame seeds and sliced green onions.
