I was just watching "Good Eats" on food network and his show topic was corn. Alton Brown was showing how to remove the corn from the cobb with a knife. He then said not to throw away the cobb. He stated that you can take it and put it on top of your charcoal for smoking. He then stated that it beats wood chips any day. This is the first I have ever heard of doing this. Has anyone ever tried it? If so what were the results?
