Sanders continued to alter his chicken recipe to get the seasonings just right. In 1939, he devised a method to cook chicken quickly because customers would not wait 45 minutes for a batch to be fried up in an iron pan. Sanders used a pressure cooker, a new invention at the time, to cook chicken in nine minutes. He found that chicken cooked in this manner turned out to be moist and flavorful. Sanders' method is still being used today.
