To prepare the glaze simply sqeeze the juice of the blood oranges into a bowl and whisk together the remaining ingredients. the glaze doent need to be cooked but should be kept at room temperature. if making ahead of time just sit the glaze out on the counter when you preheat the smoker and it will be ready by the time you need it.
Trim chicken thighs, cut any extra pieces of fat or bone fragments. if possible let thighs sit uncovered in the fridge for a few hours to dry out the skin. Once its time to season coat chicken thighs on both sides with bbq rub then let come up to room temperature.
Pre Heat pellet grill to 375 degrees F. once grill has come to temp smoke the chicken thighs skin up for 1 hour. Spray Chicken thighs with avocado oil spray every 30 minutes.
After an about one hour move the chicken thighs to a pan with 3 tbsp of butter and cook until chicken has reached an internal temp of 160 degrees F. and skin is crispy.
Brush chicken thighs with glaze every 15 minutes until they reach an internal temperature of 185 degrees F.
Pour glaze from the bottom of the pan over the chicken thighs before serving. I prefer to rest the chicken for 10 minutes before serving.
