Fred Sirieix challenges two leading chefs to tackle KFC's Zinger Burger and replicate their original top-secret chicken recipe. Tom Aikens from Muse in Belgravia and Alex Bond from Nottingham's Alchemilla have just seven days to perfect their recipes, before cooking them head to head for KFC's big bosses, who will choose a winner. As the chefs take different but equally outlandish approaches in their quests for a perfect replica, comedian Jayde Adams goes behind the scenes of KFC's factories to reveal how the famous products are really made.

Fred Sirieix sets two chefs to the challenge of replicating the Wagon Wheel, a precise combination of mallow, crumbly biscuit and chocolate. Tristan Welch, who cut his teeth with Gary Rhodes, aims to solve the problem with madcap gadgets, while Cyrus Todiwala, one of the most respected Indian chefs in the country, takes a more instinctive approach. They have seven days to perfect their replicas before a cook-off before a panel of Wagon Wheel bosses, who choose the winner. And while they're busy in the kitchen, comedian Jayde Adams goes behind the scenes to reveal how the circular snack is really made.
