So the other day I smoked three racks of baby back ribs and I used the 2-2-1 method. After the five hours they had perfect shrinkage and tasted amazing. I am going to be trying spare ribs this week and I was curious to know how people here like to cook them. I've been doing some reading and see that the majority of people use the 3-2-1 method instead or they just leave them on the smoker for 4-5 hours. I was planning on using the 2-2-1 method again but now i'm thinking differently.... What tends to produce the best product?
