Just to add to the confusion. It could just be a matter of semantics.
Barbecue or barbeque (common spelling variant)[1] (with abbreviations BBQ, Bar-B-Q and Bar-B-Que; and diminutive form barbie, used chiefly in Australia and New Zealand; and called Braai in South Africa) is a method and apparatus for cooking meat and various other foods, with the heat and hot smoke of a fire, smoking wood, or hot coals of charcoal, cooking gas, or even electricity; and may include application of a marinade, spice rub, or basting sauce to the meat or vegetables.
In British usage, barbecuing and grilling refer to a fast cooking process directly over high heat, while grilling also refers to cooking under a source of direct, high heat—known in the U.S. and Canada as broiling. In US English usage, however, grilling refers to a fast process over high heat, while barbecuing refers to a slow process using indirect heat and/or hot smoke (very similar to some forms of roasting). For example, in a typical U.S. home grill, food is cooked on a grate directly over hot charcoal, while in a U.S. barbecue, the coals are dispersed to the sides or at significant distance from the grate. Its South American versions are the southern Brazilian churrasco and the Argentine asado.
Alternatively, an apparatus called a smoker with a separate fire box may be used. Hot smoke is drawn past the meat by convection for very slow cooking. This is essentially how barbecue is cooked in most U.S. "barbecue" restaurants, but nevertheless, many consider this to be a distinct cooking process called hot smoking.
Barbecuing encompasses four distinct types of cooking techniques. The original technique is cooking using smoke at lower temperatures (usually around 240°F) and significantly longer cooking times (several hours), known as smoking. Another technique is baking, utilizing a masonry oven or any other type of baking oven, which uses convection to cook meats and starches with moderate temperatures for an average cooking time (about an hour plus a few extra minutes). Yet another technique is braising, which combines direct dry heat charbroiling on a ribbed surface with a broth-filled pot for moist heat, cooking at various speeds throughout the duration (starting fast, slowing down, then speeding up again, lasting for a few hours). Finally, grilling is done over direct dry heat, usually over a hot fire (i.e., over 500°F) for a short time (minutes). Grilling may be done over wood, charcoal, gas (natural gas or propane), or electricity.
