Rinse and pat dry the chicken wings thoroughly with paper towels. Cut and divide the wing into drummette, wingette and the tip. Discard the tip or store it for use in chicken stock. Transfer the drummettes and wingettes into a large mixing bowl.
Add in lemon zest, lemon juice, honey, soy sauce, sesame oil and sesame seeds into the mixing bowl. Toss to coat, cover and marinate for at least 1 hour.
Preheat the oven to 200 degrees Celsius and line a baking sheet with parchment paper. Tip the chicken wings and marinade onto the baking sheet then grill for 20 minutes, turning and basting the wings occasionally. Crank the heat up to 225 degrees Celsius and grill for another 10 minutes, turning and basting more frequently, until the sauce is sticky and the wings are well-browned.
