Pellet grills have been around for over 30 years but have seen a resurgence in the last few years. They can operate as a grill or smoker.
With a pellet grill, there is a hopper on the side of the grill that you will fill with food-grade wood pellets. Then to ignite, just flip the power switch on and set a temperature. An auger connects the hopper to a burn pot under the cooking grate and, as it rotates, it moves the pellets into the burn pot.
The grill also has what is called a "hot rod" inside that will ignite the pellets as they fall into the burn pot. The wood pellets burn and smoke, giving you that hardwood smoked flavor. You can cook on high heat, which is comparable to most grills on the market, or cook low and slow, truly making it the perfect middle ground.
Since a computer controls a fan to stoke the fire and the rate at which wood pellets are added to the burn pot the need to be connected to an electrical outlet when in use.
