Sometimes called charwood or chunk charwood charcoal, lump charcoal is an all-natural product made by burning trees, logs, or chunks of pure wood in a kiln with little or no oxygen. This process eliminates most of the water in the wood and, interestingly, most of the aldehydes and other smoke and flavor-producing compounds. The result is a fuel that is easier to transport and light and that burns hotter, longer, and at a more consistent temperature than wood but that imparts little intrinsic flavor. Its reliability, consistency, purity, and neutral flavor make it the fuel of choice among many grill masters from around the world.
