In the United States, people barbecue chicken, beef and pork, depending on the part of the country. Barbecuing is very popular in the Central and Southern U.S., especially in Texas with beef and Kansas City and North Carolina with pork. In the United States barbecued meat is usually covered in barbecue sauce, a type of thick, dark red sauce that often contains spices, tomatoes, and honey. Very often, American barbecue grills get heat from hickory wood.
