01 - Set oven to 425°F (220°C). Line a baking sheet with parchment or foil and position a wire rack on top if available.
02 - Pat wings dry with paper towels. Arrange on rack or directly on lined baking sheet. Roast for 35–40 minutes, turning midway, until skin is golden and crisp.
03 - Combine soy sauce, honey, brown sugar, rice vinegar, sesame oil, garlic, and ginger in a saucepan. Simmer over medium heat until sugar dissolves.
04 - Whisk cornstarch and water in a small bowl. Stir slurry into simmering sauce. Cook 2–3 minutes until thickened and glossy. Remove from heat.
05 - Transfer roasted wings to a large bowl. Toss thoroughly with teriyaki sauce to coat every piece.
06 - Return coated wings to the baking sheet. Bake for 5 minutes to allow glaze to caramelize.
07 - Serve immediately, garnished with sliced spring onions and toasted sesame seeds.
