In my horizontal I use lump in a charcoal basket as my fuel source. Then I will wrap 2 to 4 fist size chunks of hardwood, usually hickory, in heavy duty aluminum foil and poke a few holes in it. Then just throw it right on top of the burning lump. The smoke from each packet usually lasts for 30...
Man oh man how I long for a good etoufee. Or even just some good mud bugs. Around here all you can get are farm raised crawfish. I guess they are better than no crawfish at all but I sure do miss the ones we caught ourselves.
Yep as rbranstner said you'll never ever go to the grocery with the same attitude as you once did. I will always wander over to look at the meat prices, rubs, marinades, etc. I have caught myself checking the freshness of jalapenos even when I'm not smoking any ABT's.
Chisoxjim probably hit the nail on the head when he said they might have been the "enhanced" cryovac ribs. Someone in my family, who shall remain nameless, made this mistake one time and the results were exactly as you described.
