01 - Preheat oven to 425°F. Line a baking sheet with parchment paper or foil and set a wire rack on top if available.
02 - Pat chicken wings dry with paper towels. Arrange wings on the prepared rack or directly on the baking sheet. Bake for 35-40 minutes, flipping halfway, until skin is crisp and golden.
03 - In a small saucepan, combine soy sauce, honey, brown sugar, rice vinegar, sesame oil, garlic, and ginger. Bring to a simmer over medium heat, stirring until sugar dissolves.
04 - Whisk cornstarch with water in a small bowl, then stir into the saucepan. Cook for 2-3 minutes more until sauce thickens and becomes glossy. Remove from heat.
05 - Transfer cooked wings to a large bowl. Pour teriyaki sauce over and toss well to coat evenly.
06 - Return coated wings to the baking sheet. Bake for an additional 5 minutes to caramelize the sauce. Serve hot, garnished with sliced spring onions and sesame seeds.
