Germany is best known for traditional Christmas treats like Stollen and Gluhwein. But thanks, in part, to its EU protected food status, a biscuit known as “Printen” is becoming really popular. Printen originates in the city of Aachen and gets its name from the elaborately designed moulds that were used as far back as the 15th century to “print” the gingerbread-like biscuits. Nik Martin has more.
