Yotam Ottolenghi and Helen Goh celebrate the sweet things in life with Ghillie Basan as they launch their new recipe book "Sweet". In a bid to reclaim the rich culture of baking, Yotam and Helen invite us to embrace all things sweet (in moderation!) Back in the kitchen, Neil Forbes talks to Tony Singh and Struan Stevenson about their new book "The Course of History", which documents ten of the most important meals in human history. Twenty years in the making, this book explores the tradition of 'dining diplomacy', while sharing some of the recipes which have influenced major historic events.
