To barbecue means to slow-cook meat at a low temperature for a long time over wood or charcoal. In America, barbecue (or BBQ) originated in the late 1800's during Western cattle drives. The cowboys were fed the less than perfect cuts of meat, often brisket, a tough and stringy piece of meat that required five to seven hours of cooking to tenderize. Other barbecue meats used were pork butt, pork ribs, beef ribs, venison and goat.
However, barbecue was not invented in America and no one knows who invented the barbecue. The word 'Barbecue' might come from the Taino Indian word 'barbacoa' meaning meat-smoking apparatus. 'Barbecue' could have also originated from the French word "Barbe a queue" which means "whiskers-to-tail." No one is sure of the correct origins of the word.
