Rome can be understood through its cuisine, but under that broad heading, David Winner finds much to say about the Eternal City. Winner takes us on a stroll through the city as he muses on all things comestible, inviting us to imagine the River Tiber as an alimentary tract, to contemplate erotic Renaissance fruit paintings, and visit a tiramisu café where magic is surely on the menu. Along the way, Winner discusses the bloodthirsty antics of an 18th-century executioner who worked for the pope, interviews a nun who makes Eucharistic wafers, and savors true stories of immolation, architecture, and artichokes.
