not bashing on Kingsford, because we have a bunch of Kinsford up at the cabin and use it regularly, just be aware that:

"Today, KINGSFORD charcoal is manufactured from wood charcoal, anthracite coal, mineral charcoal, starch, sodium nitrate, limestone, sawdust, and borax. The wood and other high-carbon materials are heated in special ovens with little or no air. This process removes water, nitrogen and other elements, leaving almost pure carbon. "

If none of that bothers you, have at it.
