A smoker is a device used for cooking food at low temperatures over a long period of time, often using wood or charcoal to create smoke. This method infuses the food with rich flavors and helps to preserve it. Common foods prepared in a smoker include meats like brisket, ribs, and pulled pork, as well as vegetables and fish. There are various types of smokers, including electric, charcoal, and pellet smokers, each offering different advantages. Electric smokers are easy to use and maintain, while charcoal smokers provide a traditional flavor. Pellet smokers combine the convenience of electric with the flavor of wood, making them popular among barbecue enthusiasts.
