Sticky, spicy, and a little bit sweet. After you make these wings you may never go back to buffalo.
In a large bowl, whisk the Soy-Balsamic Sauce, scallions, hoisin, and Magic Paste. Set 1/2 cup sauce aside in a small bowl for basting the wings. Add the wings to the large bowl. Toss until coated. Cover the wings and reserved sauce separately; refrigerate for 1 hour.
Prepare the grill for medium heat. If using charcoal, when the coals are gray, pile them on 1 side of the grill. If using a gas grill, light 1 part of the grill and leave the other unlit.
Place the wings on the cooler side of the grill in a single layer, spacing them evenly apart. Close the grill and cook for 5 minutes. Turn the wings over; baste with the reserved sauce. Close the grill and cook for 5 minutes more. Transfer the wings to the hot side of the grill; baste with some of the sauce. Cook, turning once or twice, until cooked through, 10 to 20 minutes more; move the wings to the cooler side of the grill if the skin begins to burn. Top with gochugaru for a little more heat, if desired.
