I have a brinkman ECS smoker with not much room for smoking ribs. Will be using both grates to smoke 3 racks of st Lois ribs, each rack cut in two so that they will fit in the smoker. My question is, will be using the 3-2-1 method, can I stack the ribs on top of each other in the covered foil pan phase of this method of smoking? Will be using apple juice in the bottom of the pan.
