Place wings on foil (place the flats skin-side down) and bake 25 minutes.
Flip the wings and bake another 20-25 minutes or until golden brown. If you want a slightly crispier skin, place under the broiler for a few minutes.
While the wings are baking, place the jelly, vinegar and butter into a small saucepan over medium heat. Stir until butter melts and the jelly is well-combined. Keep warm until ready to use.
When the wings are done, remove from the oven and transfer to a large bowl.
Drizzle with the sauce and turn to coat.
Notes
Serve with your favorite dipping sauce on the side, if desired.
