Preheat your oven to 425°F and line a baking sheet with a wire rack to allow for maximum air circulation.
Pat the chicken wings completely dry with paper towels, as removing moisture is the key to achieving a crispy skin.
In a large bowl, toss the wings with baking powder, sea salt, and black pepper until they are evenly coated.
Place the wings on the wire rack in a single layer and bake for 35 to 40 minutes, flipping them halfway through.
While the wings bake, combine honey, tamari, rice vinegar, garlic powder, and ginger powder in a small saucepan over low heat.
Simmer the sauce for 3 to 5 minutes until it thickens into a glossy glaze, then remove from heat.
Toss the hot, crispy wings in the glaze, sprinkle with sesame seeds, and serve immediately with fresh cucumber slices.
