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