Smoked pork collar (neck cut) cooked with broad beans

Its composition critically involves smoked pork collar, specifically utilizing the neck cut, which undergoes a slow cooking process until it achieves maximum tenderness. This smoky main component is traditionally paired with broad beans, also known as Fava beans.
