'It was alarming': Former Great British Bake Off legend Mary Berry reveals she was 'once arrested in the US after flying with cooking ingredients'

Mary Berry has revealed she was once detained at a US airport after carrying cooking ingredients in plastic bags.

The veteran baker joined Graham Norton for a chat alongside Claudia Winkleman, her Britain’s Best Home Cook co-host on Friday's show.

As Winkleman revealed that working together “revealed Mary’s darker side”, Berry took over the story and explained that she was “arrested” 25 years ago.

Berry said: “I was going to the US to do some cookery demonstrations and was worried that there might be problems so I weighed out all the ingredients – flour, sugar – and put them all in little plastic bags.

“When I arrived at the airport the sniffer dogs made a bee-line for me. Suddenly I was surrounded by uniformed people and my assistant and I were put in separate cells. It was alarming.”

She added: “When I was asked if was going to make money from the stuff, I said ‘I do and my fee has already been agreed’.”

The former Great British Bake Off judge, 83, will front the new BBC One series, beginning on May 3 at 8pm.

Sherlock star Benedict Cumerbatch was also on the chat show to talk Doctor Strange and whether fans can expect to see him again.

Shrugging, he said: “Let that rumour take flight. This film is so shrouded in secrecy.”

Also on the show, Maxine Peake talked about doing stand-up and Friends star and Top Gear host Matt LeBlanc confessed theatre isn’t “for him”.

Calvin Harris and Dua Lipa performed new hit One Kiss before stopping by the sofa for a chat with the presenter and his guests.

The Graham Norton Show airs Friday 20 April at 10.35pm on BBC One.
