Look up Harry Soo from Slap Yo Daddy BBQ. He is an award winning pit master and achieved his hundreds on competition trophies using a Weber Smokey Joe. He has a fantastic video on how to set up the Smokey Joe for long cooks/smokes. I followed his advice to the letter and have had phenomenal results in the KK. No foil pouches, no cast iron pots with holes drilled and flour paste seals, etc. Just Charcoal and wood chunks arranged in a very specific way. Again, I have had fantastic results with his technique. Good Luck! Here is a link:
