01 - Preheat the oven to 425°F. Line a baking sheet with parchment paper and place a wire rack on top.
02 - Pat chicken wings thoroughly dry with paper towels. Toss with salt, pepper, and baking powder in a large bowl until evenly coated.
03 - Arrange wings in a single layer on the wire rack. Bake for 20 minutes, flip carefully, and bake another 15 minutes until golden brown and crispy.
04 - While wings bake, whisk Sriracha, honey, soy sauce, rice vinegar, sesame oil, garlic, and ginger in a small saucepan. Simmer over medium heat for 2-3 minutes until slightly thickened. Remove from heat.
05 - Transfer hot wings to a clean bowl. Pour the Sriracha glaze over and toss thoroughly to coat evenly.
06 - Arrange wings on a serving platter. Sprinkle with toasted sesame seeds and spring onions. Serve immediately with lime wedges if desired.
