Pellets can be used as fuel in pellet smokers or added to charcoal, gas, and electric smokers for flavor. Made of compressed sawdust. That’s all. No glue. A major advantage is that you can add pellets precisely from a measuring cup, so you can get the right amount for your smoker and no more.
Most pellets are a blend of oak and the “flavor” wood. Manufacturers do this to maintain a consistent burn, and because they say that pure varietal woods are too strong. Methinks price is also a factor.
There are a number of companies supplying pellets. My favorite supplier is BBQrs Delight brand. They have a wide range to experiment with: Jack Daniel’s, sugar maple, cherry, pecan, black walnut, oak, orange, sassafras, mulberry, alder, and savory herb.
Amazon carries pellets from BBQr’s Delight, Traeger, LumberJack, Bob Grillson, and other suppliers.
