Why KFC's fried chicken tastes different from that of every other fast-food chain

KFC's fried chicken is distinct due to its use of commercial pressure fryers, a secret blend of 11 herbs and spices, and a hand-breading technique. The recipe's secrecy is emphasized, with components stored in a vault and mixed separately for security. The chain's breading process, called '7-10-7,' ensures consistent coating and even cooking.
