Well it's been a couple of years since I've actually had the chance to sit and properly smoke a brisket (3 little rugrats at home!) So my last attempt was so bad I threw it. I figured 90 minutes per pound at around 230. So a 3 pounder smoked for 4 1/2 hrs at 225-230. Waaaaaaaay to long. Knife barely cut through it. What gives? HELP!
