While chicken is dripping, spray a large frying pan(copper bottom is what I use)with non-stick cooking spray. Heat pan over medium heat until a few drops of water sizzle and evaporate when sprinkled on the surface. Add the drained chicken pieces and sear on each side until nicely browned. Add the stick of butter, cut into several chucks if desired and allow to melt,coating the chicken pieces by moving them about and turning them carefully over a few times. Lower heat to low, sprinkle cinnamon to taste and once more move chicken pieces around, turning carefully to coat evenly. When butter begins to bubble slightly, lower heat a bit more and cover, cooking until chicken is very tender(can be cut with a fork). Turn and move chicken pieces around every 10-15 mins. until cooked to taste.
