Thaw your scallops under cool water, this won't take long, so don't water log them (yes, run the water directly over them). Preheat oven to 350 degrees. Mix up your blackening season and coat each side of the scallop. In your cast iron skillet (and on your outdoor grill burner as this will smoke up your house).....blacken the scallops for about 1 minute each side. Transfer the scallops, in the skillet, to the oven for 4 to 5 minutes. Serve!
