Charcoal briquettes are small, compressed blocks made from charcoal dust, binders, and additives. They are commonly used for grilling and barbecuing because they burn steadily and produce a consistent heat. The briquettes are designed to ignite easily and maintain a long burn time, making them a popular choice for outdoor cooking. These briquettes are often made from natural materials, such as wood and sawdust, which are carbonized to create charcoal. Some brands may include chemicals to enhance ignition or improve burning efficiency. When used properly, charcoal briquettes can provide a flavorful cooking experience for various foods.
