Smokers are like grills, but they can maintain temperatures lower and for a more extended time. The primary function of this is that the flavour from your charcoal, woodchucks, or wood pellets will penetrate the meat and give extra flavour. Did you know that you can still cook a burger and steak in a smoker low and slow? You can, and it is delicious if you want to add sear marks throw a cast iron pan in your smoker and kick up the heat for that reverse sear.
