Senator Giles Coren and vestal virgin Sue Perkins travel back to 44BC-80AD for a journey through the early days of Ancient Rome, as the culinary history series concludes. Accompanied by chef Valentina Harris, the Supersizers reside in a magnificent villa with views of the city and a marbled kitchen. Valentina prepares a range of exotic dishes, including the hugely popular but putrid smelling garum sauce - made from rotten fish innards. The Supersizers also discover the origins of pizza and pasta, while sampling their predecessor, popular snack lagana, on a visit to the Colosseum. After Giles attempts to become a gladiator and Sue takes on the role of Queen Cleopatra, the intrepid duo resolve to conquer the small island of Britannica. Arriving at Dover Beach, the pair sample British oysters while Sue becomes Boudicca and Giles enjoys a freezing cold bath. Pining for their slaves, the pair retreat back to Rome for the final banquet of the series. Joined by actor Kenneth Cranham, historian Adrian Goldsworthy and foodie Angela Pagano, the gallant Supersizers end their adventures smothered in a sea of rose petals.
