Biscotti is derived from "bis" (twice) and "cotto" (cooked). This crunchy confection has its roots in the Tuscan region of Italy in a city called Prato. Because it could be stored for a long time, biscotti was ideal for sailors, soldiers and fishermen, and it's said Columbus carried some on his voyage. Most European countries have adopted their own version of biscotti. For example, England has rusks and Germany has zwieback.
