Mix all the marinade ingredients together in a large bowl and taste. The marinade should be spicy, garlicky, and a bit sweet.
Wash the chicken wings in cold water. Pat dry with a paper towel and add to the bowl. Mix well so that the wings are well coated. Cover the bowl with plastic wrap and refrigerate overnight. Take them out of the fridge 30 minutes before cooking.
When read to broil, bring the wings to room temperature. Grease a broiler pan with vegetable oil and arrange the wings on top. (Place a foil-lined baking pan below to reduce cleanup.) Place in the oven with the wings about 3-4" away from the flames. Broil for about 5-7 minutes. Turn the wings over and broil another 5 minutes until done. (Check every once in a while to make sure you don't burn them!)
Garnish with the scallions and serve with dipping sauce on the side.
