Separate the flats and the drums discarding the wing tips
Place wings on wire rack set atop a baking sheet
Sprinkle kosher salt over the wings on both sides
Place baking sheet with wings (uncovered) in the fridge overnight
The next day take your wings out of the fridge
Setup your Big Green Egg for indirect cooking and preheat to 350° adding some wood chips for a little smoky flavor
Use a little mustard slather as a binder for your wings then cover both sides with your favorite BBQ rub
Place the wings in the Big Green Egg skin side down and let them cook for 20 minutes then flip to skin side up
Let them cook for another 20 - 30 minutes until they measure 165° with thermometer (they can be a little higher in temp)
Remove wings, sauce, and serve
