Jamie Oliver sees how local citrus fruit enhances the fresh fish netted in the turquoise waters off Sardinia. In the stunning quiet of a volcanic forest on Jeju island in South Korea, he discovers the perfect place for shiitake mushrooms to flourish. Then back home, Jamie makes an ingenious, colourful toasted bread to go with spinach, cheese and eggs for breakfast. There's a colourful salad for lunch, and shiitake mushrooms and chicken combine for a spicy Balinese curry for dinner.
