Quantities is a hard one to describe. When you start using your DrumBo we suggest using a minimum of half a basket of lump charcoal and a full chimney of lump charcoal because it’s easier and quicker to bring it to the 300F operating temp. Once you get the hang of using the DrumBo this way then you can play around using more or less depending on what you’re cooking. Smaller thinner foods use less charcoal. Bigger thicker items use more is the rule.
