What is "maccu"

Maccu, (also known as maccu di fave, and sometimes referred to as macco), is a Sicilian soup and also a foodstuff that is prepared with dried and crushed fava beans (also known as broad beans) and fennel as primary ingredients. It dates back to ancient history. The dish is now rare in Sicily, but it occasionally appears on restaurant menus there. Several dishes exist using maccu as a foodstuff, such as Bruschetta al maccú and Maccu di San Giuseppe, the latter of which may be served on Saint Joseph's Day in Sicily.
