KFC is the world's largest fried chicken fast food chain. KFC's logo KFC is the abbreviation of English KFC fried chicken, which has become a well-known brand all over the world.

in p>1931, Harlan Sanders, the founder of KFC, opened a restaurant in his hometown of Kentucky, USA. During this period, Sandoz devoted himself to studying the new method of fried chicken, and finally succeeded in inventing a secret recipe composed of eleven spices and unique cooking techniques. Its unique taste was well received by customers, and the restaurant business was booming day by day, and the secret recipe has been inherited to this day. In recognition of his contribution to his hometown, KFC awarded him the honorary title of Colonel Sanders.

Colonel Sanders, dressed in a suit, with white hair and goatee, has become the best symbol of KFC's international brand.

Colonel Sanders' success began when he was 41 years old and ran Corbin gas station in KFC. In order to increase his income, he began to make his own snacks and provide them to passers-by. Because his reputation for cooking food attracted passers-by, his business grew slowly and steadily. While his reputation was growing, Ruby Laffon, then governor of KFC, awarded him the title of Colonel of KFC in 1935 in recognition of his contribution to the catering in KFC.

The colonel's most famous specialty is fried chicken, which he carefully developed and invented. This is Deji's most popular product at present. It is cooked by Colonel after ten years' research with a magical formula of eleven spices, which makes people suck their fingers after tasting it.

The delicious fried chicken has attracted many customers. However, the traditional fried chicken method makes customers have to wait for 31 minutes before they can enjoy the food. In 1939, this problem was solved when the colonel visited a pressure cooker display. The colonel bought a pressure cooker and went home. After doing various experiments on cooking time, pressure and refueling, he finally found a unique method of fried chicken. This fried chicken under pressure is the most delicious fried chicken he has ever tasted, and KFC fried chicken still maintains this recipe of using pressure cooker.

The colonel's career faced a crisis in the mid-1951s, and the road next to his Sanders Cafe restaurant was passed by the newly-built expressway, which forced him to sell the restaurant. At that time, the colonel was 66 years old, but he was still young and didn't need to live on social welfare, which turned out to be a turning point in his career.

The colonel used his old Ford car produced in 1946, carrying his eleven spice recipes and his right-hand man-pressure cooker. He went to restaurants all over India, Ohio and KFC to sell the recipe and method of fried chicken to interested restaurants. In 1952, the first authorized KFC restaurant in Salt Lake City was established. Surprisingly, in just five years, Colonel has developed 411 chain stores in the United States and Canada, which is the beginning of catering franchise in the world.
