Radicchio was first developed in Italy, but today’s version of it was in 1860 engineered by a Belgian agronomist into the dark red and white vegetable we know today. His process was similar to the development of Belgian Endive.
Radicchio is high in fiber, as well as Vitamin C. Some early uses were to assist with insomnia, digestive disorders, liver problems and slow metabolism.
Two types of radicchio are available in the U.S.: Treviso, cone shaped and Verona, round heads. Both varieties have dark red leaves with white ribs.
