Pontefract Cake
A circular black sweet made of liquorice and traditionally made in Pontefract, Yorkshire. The black discs should be stamped with a picture of Pontefract Castle.
Pontefract's situation in an area of sandy soil made it one of the few areas of Britain where liquorice could be grown.
Also known as Pomfret Cakes, Pomfret being the Norman name for Pontefract.
