Remove all grill racks and preheat barbecue to 450°F If your barbecue comes with a rear burner use this only.
Place heavy duty tray (your broil pan base works well for this) directly on burner.
Mix together orange juice, wine, water, 1/2 orange cut into slices, 2 sprigs of rosemary and garlic cloves sliced.
Pour liquid into tray.
Now time for the chicken or turkey.
Rinse well and pat dry. Rub with other 1/2 orange making sure to separate skin from breast area and applying here as well. Cut remaining orange in half and put inside cavity.
Now break up 1 sprig of rosemary placing in and around breast area. Add another 1 or 2 sprigs to inside of cavity.
Tie legs and wings tight to body of chicken or turkey using kitchen twine (wetting twine will help keep it from burning).
Place on rotisserie and center over tray.
Cook for 30-40 min at 450°F then reduce heat to 300°F The juice in the drip pan will continually evaporate, rise and self baste you chicken or turkey so try not to lift the lid too often. Do not let the pan dry out, add extra liquid as needed. Cook for 18-20 min per lb. or until cooked through. I have also used lime juice, beer and different herbs and spices. Experiment with your favorites. You will not be disappointed.
