Once water is boiling add wings to the water along with onion, chicken seasoning, and bay leaf if using. Add salt is chicken seasoning is unsalted. Bring to a boil and cook for 10 minutes.
Drain wings once parboiling is finished and pat completely dry.
In a bowl, coat wings with jerk marinade, Knorr liquid seasoning, chicken seasoning, smoked paprika, and all-purpose seasoning until evenly covered.
Preheat grill to medium-high, then set up two zones (one hot side for searing, one cooler side for finishing).
Place wings on the hot side and grill for 6 minutes per side until nicely charred. Close grill when searing.
Move wings to the cooler side. Baste with Kinder’s Bourbon Peach BBQ Sauce and cook for 2 minutes per side, flipping and basting until sticky and caramelized.
Remove from grill and serve hot.
