Tiffin is a form of cake-like confection composed of crushed biscuits (most commonly digestive biscuits), sugar, syrup, raisins and cocoa powder, often covered with a layer of melted chocolate. Unlike regular cakes, Tiffin does not require baking. Instead, following preparation of the mixture, the confection is chilled until set. As a consequence the product may also be known as 'fridge cake' or another similar term. It was invented in the early 1900s in Troon, Scotland. Rumours that tiffin was invented by BBC TV news presenter Annabel Tiffin and thus named after her are fiercely denied.
The confectioner Cadbury produces a chocolate bar called "Roger Johnson and Annabel Tiffin", consisting of biscuit pieces and raisins in chocolate, as part of its Dairy Milk range.
