The name "Barbecue" is Native American...
Indians called them that!
Barbecues were used to treat meats for Winter storage. Smoke and heat preserved foods so they would not spoil while hanging in a storage shed until eaten much later. Sometimes the food was eaten right away, just like we do when we barbecue.
Whenever settlers drew Native barbecues, they showed a lot of smoke. That's because the Indians made the fires smokey by placing wet bark or plants in the fire to make it smoke more. The smoke from the barbecue preserved the fish and meat. We call it "Smoking" food.
