What is both a tool of empire and a sweet indulgence? What is a cleanser of sins and the basis of beer brewing? Biscuits! Lizzie Collingham's history of 'a very British indulgence' continues her unique capacity to enrich our understanding of connections between food and change in world history. Her latest book on The Biscuit follows her earlier, much acclaimed books, Curry, The Taste of War, and Hungry Empire.

Join her at our first HCV Book Club, in conversation with David Lowe. There will be an opportunity for you ask questions of Lizzie, but we also welcome questions in advance, that David can put to Lizzie. Please add your questions here by midday Tuesday 10 April.
