Barbecue pit

In the United States, barbecue refers to a technique of cooking that involves cooking pulled pork outdoors, over a fire; often this is called pit barbecue, and the facility for cooking it is the barbecue pit. This form of cooking adds a distinctive smoky taste to the meat; barbecue sauce, while a common accompaniment, is not required for many styles.

Often the proprietors of Southern-style barbecue establishments in other areas originate from the South. In the South, barbecue is more than just a style of cooking, but a subculture with wide variation between regions, and fierce rivalry for titles at barbecue competitions.

There are 3 ingredients to barbecue. Meat and wood smoke are essential. The use of a sauce or seasoning varies widely between regional traditions.

The first ingredient in the barbecue tradition is the meat. The most widely used meat in most barbecue is pork, particularly the pork ribs, and also the pork shoulder for pulled pork. The techniques used to cook the meat are hot smoking and smoke cooking. These cooking processes are distinct from the cold smoking preservation process. Hot smoking is where the meat is cooked with a wood fire, over indirect heat, at temperatures between 120 and 180 °F (50 and 80 °C), and smoke cooking is cooking over indirect fire at higher temperatures. The long, slow cooking process take hours, as many as 18, and leaves the meat tender and juicy. Characteristically, this process leaves a distinctive line of red just under the surface, where the myoglobin in the meat reacts with carbon monoxide from the smoke, and imparts the smoky taste essential to barbecue.

The second ingredient in barbecue is the wood used to smoke the meat. Since the wood smoke flavors the food, the particular type of wood used influences the process. Different woods impart different flavors, so the regional availability of the various woods for smoking influences the taste of the region's barbecue.

Stronger flavored woods are used for pork and beef, while the lighter flavored woods are used for fish and poultry. More exotic smoke generating ingredients can be found in some recipes; grapevine adds a sweet flavor, and sassafras, a major flavor in root beer, adds its distinctive taste to the smoke.
