BBQ, barbecue, or however ya want to spell it is cooking low and slow, low temperatures, usually with some wood smoke, for very long times. No one is really sure who or where it originated, but it was born out of necessity as a traditional method of cooking, which renders a tough, fatty or undesirable cut of meat, like brisket or pork butt, into some of the stuff you’ll ever put in your mouth! The process is a combination of science, know-how, art and some luck.
