Gas smokers are outdoor cooking devices that use propane or natural gas as a fuel source to generate heat and smoke. They typically consist of a cooking chamber, a burner, and a wood chip tray, allowing users to infuse food with smoky flavors while maintaining precise temperature control. These smokers are popular for their convenience and ease of use compared to traditional charcoal or wood smokers. With adjustable heat settings, gas smokers can be used for various cooking methods, including smoking, roasting, and grilling, making them versatile tools for outdoor cooking enthusiasts.
