Raymond visits a very special house and garden, Highgrove. Beloved home to King Charles III with impressive gardens and important educational centres, it's a truly magical place. Exploring the grounds Raymond finds himself in his favourite space, the walled gardens where he chats to Mel about the organic principles of the estate and how Charles built the gardens from nothing. Using fresh greens from his own garden, Raymond makes a bistro classic Lyonnaise salad. Head chef Luke uses some of his own favourite ingredients to cook for Raymond, serving up Rosemary chicken with butternut squash and chilli. The perfect dish for autumn. Keen to see the important work of the Prince's foundation, Raymond heads to the dye garden to meet Kasia and find out the range of educational programmes on offer. Inspired by the wonderful colours he sees in the garden, Raymond makes baked figs and pain perdu.
