Charcoal briquettes are manufactured with additives for consistent burn, while lump charcoal is made directly from hardwood and burns hotter and faster. Lump charcoal generally imparts a cleaner flavor to food.
Charcoal briquettes are manufactured from a mixture of wood byproducts, coal dust, and additives like binders, accelerants, and sometimes even lighter fluid. This manufacturing process results in a uniform shape and size, leading to a more consistent and predictable burn. Briquettes typically burn longer and at a lower temperature than lump charcoal. However, the additives can sometimes impart a slightly chemical taste to the food.
Lump charcoal, on the other hand, is made by burning hardwood in a low-oxygen environment. This process leaves behind almost pure carbon. Lump charcoal lights faster, burns hotter, and produces less ash than briquettes. It also imparts a cleaner, wood-fired flavor to food. Because it's made from natural wood, the size and shape of the pieces are irregular, which can make temperature control slightly more challenging.
When using lump charcoal, invest in a charcoal chimney starter. It will help you light the charcoal quickly and evenly without the need for lighter fluid, preserving the pure flavor of your food.
