Like other grills, pellet grills list cooking area two ways: primary cooking area, which refers to the main cooking grate, and total cooking area, which is the main cooking grate plus any secondary racks. However, since pellet grills are primarily indirect cookers, there really is no difference between cooking on the main rack or the upper rack&em;the temperature should be the same. Therefore, a smaller pellet grill with a primary grid of 450 square inches and an upper rack of 125 square inches may be a better option than a larger grill with only a 500 square inch primary grid.
To be sure, there are pure “smoker” and pure “grills” but there are some exceptionally well-designed hybrids. I bought a Memphis Elite last year, and it is AWESOME! I made a pulled-pork masterpiece two months ago that was absolutely delicious… 8 hours on low temperature (225) then an hour on open flame (switching from a “smoker” insert to an “open-flame’ insert at 700 was easy) and it was awesome!
Although these are marketed as grills, they do much more, including baking or roasting. Because they heat by convection, you might not get the grill marks that a gas or charcoal grill will give you, but you also won’t have the flame-up problems. While many pellet grills offer high cooking temperatures, the maximum depends on ambient temperature and wind. Many users wrap their grills in special insulating covers to help maintain heat, reduce fuel use, and reach the higher temperatures they desire.
