been doing a lot of reading on the different posts. i have a grasp of the 3-2-1 method for spares and understand this method will vary depending on preference, but is there something you should be looking for in the ribs that will signal the time to foil? in other words, aside from using the standard 3 hours, what are you looking for in the ribs to know it's time to foil? just trying to understand the process and not go by the dreaded "time". i feel i have got the pork butt's down pretty well and am venturing into the ribs this weekend. any feedback would be appreciated. thanks in advance!
