Lucy Worsley, chief curator of the historic royal palaces, ends the series by looking at the room we now spend the most money on, but was once thought of as the most dirty, dangerous and undesirable room in the house: the kitchen. From baking bread in a Tudor kitchen to spit-roasting mutton with a dog to doing a week's Victorian re-cycling to trying out 1950s labour-saving gadgets, Lucy tracks the changes that have turned the kitchen from a room of hard work into the appliance-packed room we know today.
