The sparkling waters of Sardinia are full of delicious seafood, and in this week’s programme Jamie Oliver shows how to make the catch of the day even better with local citrus fruit (everyone knows lemon and fish are best mates!).

Meanwhile, in South Korea, he finds out what conditions are required to grow the perfect shiitake mushrooms (the fungi theme continues later with a shiitake and chicken Balinese curry). On the home front, the cheerful chef reveals a colourful way to jazz up breakfast: multi-hued bread! The rainbow theme continues with a lovely lunchtime salad. All things bright and beautiful!
