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