Hi just finished building a smoker out of an old steel fridge. I purchased a smoke daddy pellet hopper for it, I smoked my first couple of racks in it this weekend. It held 225 within 5 degrees for the whole smoke. My problem is when I took them out of the foil after the 2-hour wrap part was they were falling apart. these were full spare ribs and this has never happened to me before using any of the other smokers I have owned. Should I just reduce the wrap in foil part by an hour?
