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