From the advice of many on here, I bought some mesquite and oak chunks for my Smokin It #1 smoker instead of the chips I planned on using. I bought the chunks from Lowes ($8 for 700 cu. in.). But, quite a few pieces have bark on them. Is it absolutely necessary to remove the bark? I don't have any saws or axes so I have no way of removing the bark and don't want to spend any more money on this new hobby than I have to. So what should I do? Use the pieces with bark on it and don't worry about it, or should I stick to using chips?
