Don’t be fooled: Mary Berry might seem like a sweet and doting grandmother (complete with an array of delicious homemade cakes), but she’s also a badass businesswoman, a talented baker, and a seasoned TV star.

Still, though… we always assumed that Berry’s controversial – and now infamous – Spaghetti Bolognese recipe was the closest she’s ever come to committing an actual crime.

So you can imagine our surprise when Berry recently let slip that she was once locked up in a cell on suspicion of drug smuggling.

Sitting down to chat about her new TV programme, Britain’s Best Home Cook, on The Graham Norton Show, Berry somehow ended up on the topic of US customs.

And, much to Norton and the audience’s surprise, the ‘Queen of Cakes’ went on to explain that she was arrested after airport security mistook the bags of sugar and flour she was carrying in her luggage for class A drugs.

“I was arrested 25 years ago. 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,” said Berry.

Mary Berry was once arrested for drug smuggling - and her response was beyond brilliant
