The Teacake is a flat, roughly circular item with a diameter of about 15cm made out of bread, with a smooth brown upper surface and a somewhat lighter
underside.
If the item contains currants then it is a Currant Teacake.
When sliced roughly in half and filled with chips then it becomes a
Chip Buttie.
It doesn't have currents*!
(not if tha's from Barnsley)
