control your temperature and control your liquid and you will get what you crave, bones falling off. I use the 3-2-1 method that so many others have mentioned. 3 hours at 180 use a mix binder (worsestershire sauce and mustard) and your rub on all over. Let it absorb smoke and no peeking. You are smoking not grilling. Make sure your probe is in the meet and not touching the bones. After three hours it should reach 160-165f. If it doesn’t wait! Then wrap in foils, ideally three layers (as bones can break your foil) and for each rack individually wrapped, add 8 ounces of apple juice or half and half of juice and vinegar. If you like the southern style with sweetness on it warm up some honey, place a thin layer on your ribs and brown sugar on top. Set the heat to 225 while doing this. Seal those ribs well in the foil and 2 hours. Ideal temp of your ribs at the end of this process is 205F. Finally remove the ribs from the foil very carefully as it might break. Place on the grates, rub your sauce and let it ticken for 30 minutes. You will have the ribs you crave.
