Preheat your oven to 400°F and line a baking sheet with a wire cooling rack to allow air circulation.
Pat the chicken wings thoroughly dry with paper towels to ensure the skin gets maximum crispiness.
In a large bowl, toss the wings with baking powder, sea salt, and black pepper until every wing is evenly coated.
Place the wings on the wire rack in a single layer and bake for 35-40 minutes, flipping halfway through, until golden brown.
While the wings bake, combine honey, tamari, minced garlic, grated ginger, and rice vinegar in a small saucepan over medium-low heat.
Simmer the sauce for 3-5 minutes, stirring occasionally, until it thickens into a glossy, sticky glaze.
Remove the crispy wings from the oven and transfer them to a clean bowl, then pour the warm glaze over them and toss to coat.
Garnish with sesame seeds and thinly sliced green onions before serving immediately.
