Well another thread here got me thinking. What does wood look like after it is spent from smoking. I have a vertical propane smoker so was wandering what chips and chunks would look like after they were done producing smoke. I am new to the art but after using chunks for the first time they looked a lot like charcoal. Not sure if they should have looked like this or should they have turned to ash? What about chips? Anyone have pictures? I am assuming that based on what your wood looks like after a smoke you can tell the quality of smoke that you produced? Accurate? Thoughts? Opinions?
