Wurstbrot
A Wurstbrot is a slice of bread spread with slices of lunch meat or sausage. Additionally, the bread may be buttered to taste. It is a very simple and typical German type of sandwich, generally home-made, eaten cold, and popular as a snack, packed lunch as well as for breakfast or supper.

With a standard electrode potential (SEP) of −0.76 volts, zinc is used as an anode material for batteries. (More reactive lithium (SEP −3.04 V) is used for anodes in lithium batteries ). Powdered zinc is used in
