Preheat the broiler. Toss the split chicken wings in oil and sprinkle with salt and pepper.
Broil about 4 inches from the heat until crispy and brown (about 10 -12 min.) Remove from oven and flip the wings over. Broil the other side for about 8 min.
While wings are broiling, put the cranberries into a food processor and pulse until finely chopped.
In a large skillet, combine the cranberries, chili sauce, water and 2 of the scallions. Bring to a boil, then reduce the heat and simmer until the sauce has thickened.
Remove from heat and strain the sauce through a sieve into a medium bowl, pressing to release as much liquid as possible. Return the liquid to the skillet and simmer until the sauce has reduced and become a thick and shiny glaze.
Toss the wings in the glaze. Return to a baking sheet and broil once again, for 3 - 5 minutes, watching carefully to avoid burning.
Garnish with the remaining chopped scallions and serve hot.
Notes
When preparing the cranberries for the glaze, bring them just to the boiling point, then reduce the heat and simmer until the sauce has thickened. If you boil cranberries too long, they will become bitter.
