Blumenthal helped to create a picnic hamper for the Jubilee that helped around 12,000 people enjoy a picnic in the grounds of the Buckingham Palace.
Blumenthal described the event, saying: "On the day I was driving around the outside of the palace and we could see thousands of people queuing, they were queuing and lapping themselves and (all I could see was) picnic hampers."

Hampers on the day included classic British dishes such as coronation chicken and Eton mess, cheese boards and a number of cakes.
