I wrapped it in some foil and put it on the upper rack of my grill at about medium. The temp got up to 400 degrees and I let it cook for 20 minutes. I turned the grill off and let it sit in the hot grill for another 20 minutes. Our guests started arriving so I had to start shredding. It had a good taste but was a little bit more dry than any of the butts I have ever done before (dozen or so). After shredding, I mixed it with about 1/4 cup of the vinegar mop. Our guests loved it saying that it beat anything they had in a restaurant...however, I knew it could have been a little bit better.
Something was definitely off on this smoke. Besides taking forever to get to temp, the wood didn't turn to ash either. I had three small chunks of wood totalling about 2.5oz of wood. One chunk was ash but the other two were charred..heavily charred..but not a pile of ash.
