Can you smoke catalpa tree beans?

Of course you can smoke it! I have found that the effects are better though if you let the dried beans soak in a bowl with some Apple cider vinegar until it evaporates and dries the bean back out. Don't forget to break the bean into 3 or 4 1 1/2 or 2 inch pieces before soaking. Cut it up fine after the soak, and enjoy the nice smooth flavor!
