Have you ever felt the urge to share exactly the same culinary experience as your ancestors? Do you care what ancient Roman bread tasted like? Or what a 16th Century courtier smelt as he lifted a slice of roast beef to his mouth? Would you understand yourself, or today’s food system, better if you did? And if the closest you come to experiencing the past is watching period dramas on television, are you bothered by whether the pigeon is actually chicken - or the fish, cream cheese? How real do we want the imaginary to be? Emily Thomas asks what we can learn about the past and present from the painstaking reconstruction of old recipes. Four people who dedicate their lives to recreating historical dishes make their case: An archaeologist tirelessly trying to uncover the secrets of the bread of Pompeii in Italy; The food stylist on the film set of the globally popular period drama Downton Abbey; An historian earnestly roasting beef at a Tudor palace; and a Polish chef desperately trying to preserve traditions he fears are becoming lost.
