Line a broiler pan or rimmed baking sheet with foil and coat with cooking spray.
Pat chicken dry. Place on the prepared pan, skinned side up. Mix scallions, ginger, oil, lime zest and juice, cinnamon, salt, pepper, nutmeg and cayenne and spread on the chicken. Cover and refrigerate for 2 to 24 hours.
Preheat broiler to high.
Broil the chicken on the pan until an instant-read thermometer inserted in the thickest part registers 165 degrees F, 15 to 25 minutes.
