1. A Taste of History: The Origins of Radicchio
Radicchio, with its striking red and white leaves, is a cultivated variety of chicory (Cichorium intybus), hailing from the Veneto region of Italy. Its story is rooted in Italian agricultural innovation. While wild chicory boasts ancient origins, the modern radicchio we recognize today emerged primarily through careful cultivation. Legend has it that Radicchio di Treviso, the most famous variety, was developed in the 15th century, using a technique known as “forcing,” where the heads are grown in the dark to reduce bitterness. Traditionally a staple in rustic peasant dishes, radicchio added a unique flavour profile to simple meals. Over time, its appeal grew, and today, radicchio is a beloved ingredient in Italian cuisine and is increasingly appreciated worldwide.
