I ran into big problems this weekend with an overnight cook. It was unusually humid here in Ohio all week and all I can figure is that the Kingsford got a bit damp and failed to light. Here's the scoop, let me know what you think.
Did my 2nd overnight this last weekend, smoking four 6.5# butts. Started the WSM at 9:30 pm with a full ring of unlit and 25 lit. Lid temp settled in at about 200 so I closed the vents to 25% and put all 4 butts on at 10:00 pm. Checked at 10:45 and again at 11:30 pm and the lid temp was steady at 225, so I went to bed.
I checked the temp at 7:30 am the next morning and the lid temp had crashed to 140 or below (my thermometer only goes down to 140). I quickly stirred the coals (there were lots of unlit coals in the WSM), opened the vents, then added 15 lit coals. This brought the temp up to 225 and I was able to finish the 4 butts. It took a total of 20 hours to get the 4 butts to 190 but I obviously lost lots of time with my near overnight catastrophe. The results were fine, the butts pulled easily and tasted great.
