Chef James Martin shares his love of puddings. Each week he visits places from his culinary past to show the sources of his best dessert recipes, before returning to his kitchen to cook up some fantastic sweets, helped by Will Torrent, his assistant chef. In this programme James returns to where he grew up and first started cooking, Castle Howard in Yorkshire. Along the way James also pops off to investigate issues related to this edition's theme of Best of British. He attempts to save some British classics by re-inventing them and tries to solve the mystery of the origin of the Sticky Toffee Pudding recipe.
