I was cooking ribs and a brisket over the weekend, but couldn't get any smoke from the wood chunks I used. I got my Egg up to 250 degrees and put a couple of apricot wood chunks into the Egg, but I never got any smoke. Even after cooking for 4 plus hours, there was still no smoke. I replaced the wood chunks with wood chips soaked in water. The wood chips smoked, but for only for a short period of time. What is the best way to get smoke using wood chunks and wood chips? How do you get the smoke to last?
