Pellet smokers (aka pellet grills, wood pellet smokers, or pellet smoker grills) are on the newer side of meat-smoking technology. Pellet smokers use, you guessed it, wood pellets as fuel in an otherwise electric setup. An electric auger and self-regulating temperature gauge work in tandem to feed more pellets into the firepot to maintain a steady temperature and put out tons of flavorful smoke.
