The Wikipedia has the following information about this codepoint:
Fried chicken, also known as Southern fried chicken, is a dish consisting of chicken pieces that have been coated with seasoned flour or batter and pan-fried, deep fried, pressure fried, or air fried. The breading adds a crisp coating or crust to the exterior of the chicken while retaining juices in the meat. Broiler chickens are most commonly used.
The first dish known to have been deep fried was fritters, which were popular in the European Middle Ages. However, the Scottish were the first Europeans to deep fry their chicken in fat. There is an English cookbook from 1736 which mentions fried chicken, the “Dictionarium Domesticum”, by Nathan Bailey. Meanwhile, many West African peoples had traditions of seasoned fried chicken (though battering and cooking the chicken in palm oil).
