Make the marinade. Stir together garlic, salt, soy, hoisin, honey, sesame oil and cayenne or Siracha
Add wings to marinade and mix well. Marinade at least 30 minutes to overnight.
Heat oven to 425°F. Line a large shallow baking pan with foil and lightly oil it.Spread wings and any sauce that fell to the bottom of the bowl out on the prepared baking pan in one layer.
Roast, turning over once, until cooked through, about 35 minutes. Transfer wings to a large serving bowl* and toss with sesame seeds and scallion.
If wings need more color, broil for a couple minutes on high heat or finish the wings on the grill, decrease baking time by 5-10 minutes
