Tap the chicken wings with a kitchen towel to make them as dry as possible.
In a bowl mix together the cornstarch, garlic powder, onion powder and salt. Add this mixture to the chicken wings and coat them well.
Line your air fryer tray with parchment paper. Place the chicken wings in a single layer leaving some space in between so they can crisp up. You may have to air fry in batches.
Air fry at 180°C (350 F) for 20 minutes, then at 200°C (400 F) for 10 minutes. Flip every 10 minutes, to ensure even cooking.
While the chicken wings are frying, prepare the sauce. In a saucepan, add all the ingredients for the sauce. Mix and bring it to a gentle simmer. Cook on low heat until the sauce thickens.
Once the wings are done, coat them thoroughly with the sauce.
Garnish with spring onion greens and sesame seeds (optional). Enjoy them hot.
