The secret ingredient in the famous Bakewell pudding recipe will never be revealed, an outgoing staff member has said.
Pauline Dinsdale is retiring after working at the Old Original Bakewell Pudding Shop, in the Derbyshire town, for 21 years.
She had previously managed the shop and more recently, she educated tourists about the delicacy.
When she appeared on BBC Radio Derby, she wouldn't be drawn on the secret ingredient.
"[When I started] I was taken very firmly to one side and impressed with the secrecy of [the recipe]," said Ms Dinsdale.
"We have very bizarre guesses at what the secret ingredient will be. Everything from salt to treacle, honey, really weird things, but we don't tell."
Not to be confused with Bakewell tarts, the puddings have been made in the Peak District town since the 1860s.
It is belived about 8,000 are purchased each week during the summer.
