Before buying, please note that pellet smokers need access to electricity to run the digital controller, the auger that transports the pellets to the firebox, and the convection fan that circulates the air in the cooking chamber. These cookers can use a lot of pellets at high temps. At high temps there is little or no smoke, and at low temps smoke is unavoidable. So if you want to cook, say, a chicken breast low and slow to retain juices, but you don't want any smoke flavor, you're outta luck. If you want to torch a thin burger to get a crunchy crust and add a little smokiness, you'll get great smoke flavor, but it is hard to get the crust. But if you want killer ribs, bacon, smoked salmon, etc., pellet burners are hard to beat for convenience and quality.
Barbecuing and grilling meats to the perfect temperature, texture and doneness is a skill that is acquired over years and years of practice. There is a lot that goes into making a good BBQ than just good seasoning and fresh meat, and any pit master will agree. There are just so many aspects you have to learn how to control: the temperature, the smoke, the placement, the ratios and so on. But you are lucky that this is new of yesterdays.
Pellet grills preheat quickly, so you can start cooking almost immediately, and the pellets are available in a number of woods, for different smoke flavors. The smoke has a subtle wood-fired flavor with less of the acrid flavor that comes from standard wood or charcoal. For the maximum smoke flavor, it’s best to cook at a temperature lower than 250 degrees, while higher temperatures cook faster with less smoke.
