GRIDDLE WITH SMOKE VENTS
A griddle is configured to drop in place of (or on top of) a normal cooking grate of a pellet grill while maximizing heat capture and maintaining proper exhaust flow. In this way, aspects of the invention ensure stable operating temperatures and/or even cooking of food while imparting smoke flavors from burning wood pellets into the food. The griddle includes a cooking surface upon which to cook the food and a smoke trap to allow airflow through the griddle while directing smoke and exhaust gases either toward the food or away from the food, depending upon the orientation of the griddle in the housing relative to an exhaust path of the housing.
