lump charcoal and charcoal briquettes?]
Charcoal is made by burning wood with very low oxygen levels. This leaves mostly carbon. In this form, it is known as natural or lump charcoal. It will be of irregular shaped pieces of wood broken up. If you shake the bag, it sounds like the tinkle of broken glass. Briquettes are different. The charcoal is ground into a powder and then additives are introduced. The additives can include starches, coal dust, oil products and other binders. Under high pressure, the ground charcoal and additives are formed to the regular shapes that are familiar to us. The advantage touted by the manufacturers of briquettes is the consistency of the product in heat output and burn rates. Lump charcoal has a higher BTU rating per pound and is preferred by many barbecuers. Never use the easy-light type charcoals for slow cooking. They have additives that must be burned off at high heat and if used in a smoker will give your barbecued meat nasty flavors.
