Famous for his experimental dishes such as snail porridge and bacon and egg ice cream, Blumenthal said medication initially dulled his culinary imagination.

He was diagnosed after being admitted to hospital in November 2023 and said he is now more involved with the The Fat Duck than for years.

“When I first came out of hospital the medications were so strong I was zombified – I had no energy at all,” he said.

“As my medications have been changed and my levels of self-confidence and self-awareness have gone up I realise my imagination and creativity is still there.

“It was at levels that were so extreme before… looking back I can remember during my manic highs I was interrupting myself with ideas.”
