Whisk together the brine ingredients in a large bowl. Add the wings, cover and chill for 4 to 6 hours.
Prepare the blue cheese dressing by combining all the ingredients in a bowl. Cover and refrigerate for at least 2 hours or as long as 24.
Combine the rub ingredients in a food processor or spice grinder until a fine texture is achieved. Transfer the wings from the brine to a half-sheet pan. Shake off most of the brine while doing so, minimizing the liquid in the pan. Discard the brine. Sprinkle one side of the wings with half of the rub mixture. Turn the wings over and sprinkle the other side with the remainder. Let the wings rest at room temperature for about 20 minutes before grilling them.
Prepare the grill for direct grilling over a medium fire, about 350°F.
Transfer the wings to the grill grate. Grill them with the hood closed, turning a couple of times along the way, until cooked-through. Total cooking time should be about 20 minutes.
Transfer the wings to a platter, sprinkle with chopped parsley, and serve with the blue cheese dressing.
You can grill these wings over a gas fire with the main burners on MEDIUM, but a charcoal fire will enhance the chile crust.
Place a thin load of charcoal in the Hybrid Fire Grilling Drawer (single file briquettes in each channel or roughly 1/4 full with lump charcoal). Start the charcoal fire with the main burners, and then turn them to LOW. Wait for the coals to ash over and all visible flame from the charcoal to subside before grilling the wings. Your desired grilling temperature is about 350°F.
