After doing the break in cycle on Friday, I had the time on Sunday to do my first smoke with my new Yoder YS640S. Nothing extravagant ... just a few racks of St. Louis cut pork ribs. I seasoned them up with Meat Church's Honey Hog rub, and smoked them for 6 hours with Lumberjack brand "Sweetwood" pellet blend. At hour five I lightly sauced them. The cook went well; this beast holds the set temperature with ease. And the Fireboard system that it has? Where has this been my whole life??? I'm pleased with this smoker!
