Honestly, and I'm sure I'll get beat down with a stick on this one, but I don't think it really matters what you add in the can as the flavor really doesn't cook through. One exception is the fact that different solutions boil at different temperatures. And if you are cooking anywhere near 300, even that doesn't matter.
With that said, if you have a tall enough smoking chamber, you can use the large cans of baked beans; emptied of course, and filled with whatever elixer you desire.
