I got a pork butt at the store yesterday and cooked it today, we started it in the crock pot this morning for 4 hours then put it in the double barrel smoker for about 5 more. It spent the last couple hours wrapped in foil.
I put some Tony Chachere's rub on it and cooked it fat side up. A quick sample tastes almost like ham.
There was a post that suggested the Chacehre's here a while back and was surprised to see it available in several countries. A search didn't turn it back up.
