So doing a long cook on Saturday of pork butt. 3 6+ pound butts. I stopped at Publix yesterday and got a back of their lump charcoal after reading some good reviews on the Whiz and wasn't a lot of options in Franklin, TN. So question is, is 8.8 lbs enough to do this cook or should I grab some more? If anyone in the Franklin/Nashville has good lead on some really good lump, bring it on!
