In food, there are household names. And then, there is Delia Smith.

So synonymous is she with cooking that her first name was included in the Collins English Dictionary in 2001. For four decades, her TV cookery programmes were primetime viewing, and when they ceased in 2013, she moved her cooking lessons online. She has sold more than 21 million copies of her recipe books. Her seasonal recipes were so popular that supermarkets would run out of ingredients when she cooked with them. - Notably cranberries in 1995. So influential were her books and broadcasts that Queen Elizabeth II made Delia Smith a Companion of Honour.

At Christmas, Sheila Dillon invites Delia, now 81, into her kitchen to reflect on her long career in food and cooking, but also to talk also about other passions. Her lifelong interest in spirituality and philosophy as reflected in her 2022 book, 'You Matter', politics, and football, and her dedicated work to make Norwich City Football Club a food destination.

Jamie Oliver and Angela Hartnett tell Sheila about the legacy Delia has left on their own careers in food. Cooking teacher Angela Holding bakes Delia's sticky toffee pudding and talks about the legacy Delia's books have had on aspiring cooks everywhere.

Presented by Sheila Dillon.
