I have been smoking for a little over a year and decided to build an ugly drum smoker. I tested it out on some ribs and a whole chicken. I got the temp to hold steady but after a couple hours I noticed this black slime on all the food. I think it is coming from moisture from the lid dropping down on to the food. I do not know why is it black though. I read about the wood might be wet, which it possibly is, but don't people also soak their wood anyways? I have two exhaust tips on the lid. Any help would be greatly appreciated. Hoping to get this thing fixed before Thanksgiving. Thanks.
