What is one key feature of an offset smoker?

The defining characteristic of an offset smoker is that the firebox is located beside the cooking chamber. This design allows for indirect heat cooking, where the heat and smoke from the firebox flow into the separate cooking chamber. The separation of the firebox from the cooking area helps maintain a consistent temperature throughout the cooking chamber, providing the ideal environment for low-and-slow barbecue cooking. The side placement of the firebox also allows for better control over the smoking process, as the cook can adjust airflow and heat without directly affecting the food being cooked.

In contrast, other options do not specifically represent the unique construction of an offset smoker. For instance, having the cooking chamber above the firebox is more typical of vertical smokers, while utilizing electric power is characteristic of electric smokers, which do not rely on wood or charcoal for heat and flavor. A built-in thermometer, while a useful feature, is not exclusive to offset smokers and can be found in many types of smokers and grills.
