South Side and West Side in Chicago In 1954, the aquarium smoker, which is named after its resemblance to a
fish tank, was invented in Chicago. They are fully enclosed except for a metal chimney that vents the smoke outside, allowing for fully indoor cooking. Glass panels on the sides of the smoker allow the cook to see inside. The wood for smoking the meat is typically placed below, allowing it to cook quickly.
Rib tips, the cartilaginous end pieces left from butchering
St. Louis–style ribs, became popular in the South Side of Chicago because of their low cost. The gelatinousness of the rib gives it a chewy exterior when cooked. The establishment of the meatpacking industry in Chicago, especially the
Union Stock Yards, also contributed to the choice of cuts prepared in the South Side, where off-cuts of meat were cheaply available.
Hot links are commonly served in combination with rib tips, as "tip-link" barbecue. This combination is typically served with
French fries and sliced white bread.
North Side In the North Side, barbecue restaurants typically use
rotisserie smokers and local woods like
applewood to prepare their meat. North Side barbecue sauces are also tomato-based but are typically thicker than South Side sauces. North Side restaurants typically focused on more expensive cuts of meat, such as
pork butt and
brisket. == Notable people ==
