In the bowl of a food processor combine the marinade ingredients until smooth. You can also do this in a blender. Add peppers if desired for heat.
Place the marinade and chicken in a zip top plastic bag. In the refrigerator, marinate for 1 hour to overnight.
Preheat oven to 425 degrees Fahrenheit with the rack in the middle. Line a baking tray with tin foil. Place the wings on the baking tray in a single layer.
Bake for 45 minutes, or until the wings are cooked through. Garnish with cilantro and serve immediately.
