Gingerbread Sydney Opera House

Gingerbread is a term used to describe a variety of sweet food products, which can range from a soft cake to something close to a ginger biscuit. What they have in common are the predominant flavors of ginger and a tendency to use honey or molasses (treacle) rather than just sugar. They probably also share a common history.
Etymology
Originally, the term gingerbread (from Latin zingiber via Old French gingebras) referred to preserved ginger. It then referred to a confection made with honey and spices. Gingerbread is often used to translate the French term pain d'épices (literally "spice bread") or the German term Lebkuchen (whose literal meaning is unclear).
