Barbecue pits are log-burning drums with air vents that sort of resemble oil barrels turned to one side. Barbecue pits, also commonly referred to as smokers, aren't really 'pits' at all. In fact the 'pit' refers to the cooking area where various meats and vegetables are cooked. A large metal fire box sits underneath the pit. This is where savory smoke is produced and infused into the meat via flavored wood. A water pan situated within the pit keeps the meats, vegetables or cheeses from drying out. Barbecue pits can be used to smoke a variety of beef jerky, turkey jerky and smoked fish, cheese, beef and lamb. BBQ pits cost between $500 and $6,000 online.
