 When it was introduced to the American South , fried chicken became a common staple . Later , as the slave trade led to Africans being brought to work on southern plantations , the slaves who became cooks incorporated seasonings and spices that were absent in traditional Scottish cuisine , enriching the flavor . Since most slaves were unable to raise expensive meats , but generally allowed to keep chickens , frying chicken on special occasions continued in the African @-@ American communities of the South . It endured the fall of slavery and gradually passed into common use as a general Southern dish . Since fried chicken traveled well in hot weather before refrigeration was commonplace , it gained further favor in the periods of American history when segregation closed off most restaurants to the black population . Fried chicken continues to be among this region 's top choices for " Sunday dinner " . Holidays such as Independence Day and other gatherings often feature this dish .
