Abstract: The disclosed embodiments provide a temperature controlled charcoal grill and smoker that enables users to better control the cooking and smoking temperature relative to previous solutions. In some embodiments, for example, a user may place a divider in the interior of a fuel basket to coarsely adjust the amount and type of solid fuel used to heat a food-cooking enclosure of the temperature controlled charcoal grill and smoker. In addition, the user can also position a heat deflector tent above one or more heat transfer openings in a grease tray to further adjust the cooking and smoking temperature. Further still, the user can provide even finer control (including closed-loop control) over the cooking and smoking temperature using a controller that controls the speed of a fan that directs combustion air into the fuel basket.
