It was a store bought sauce from a local meat market that we have here. I probably wouldn't buy it again. It wasn't my favorite. I tend to lean towards Sweet Baby Ray's. The chipotle flavor is one of my favorites. Good amount of sweet and heat. I don't have one, but it looks like they do!
Like I was telling @bdmillergallery, the number of accessories you can get for the Weber Kettle is insane!
