These manufactured fuel pieces, commonly used for outdoor cooking, consist of compressed charcoal, often combined with additives to aid ignition and maintain consistent heat. They provide a convenient and readily available heat source for grilling and barbecuing.
The accessibility and predictable burn times of these products contribute to their widespread adoption. They offer a relatively clean and controlled method for preparing food outdoors, enabling consistent results across a range of culinary applications. Historically, the rise of suburban living and outdoor recreation spurred the demand for easily obtainable and manageable fuel sources, solidifying their position in the consumer market.
