Radicchio Red

Radicchio is a leaf chicory (Cichorium intybus, Asteraceae), sometimes known as Italian chicory. It is grown as a leaf vegetable which usually has white-veined red leaves. It has a bitter and spicy taste, which mellows when it is grilled or roasted. It can also be used to add color and zest to salads. The varieties of radicchio are named after the Italian regions where they originate: the most ubiquitous variety in the United States is radicchio di Chioggia, which is maroon, round, and about the size of a grapefruit. Somewhat less common in the States is the radicchio di Treviso, which resembles a large Belgian endive: other varieties include Tardivo, and the white-colored radicchio di Castelfranco, both of which resemble flowers and are only available in the winter months. In the same way that the Parmigiano-Reggiano cheese-makers of Parma, Italy, have sought to protect the name "Parmesan" to signify only cheeses made in their region under the supervision of a regulating body, so too have the radicchio farmers of the Veneto sought to protect the names of some radicchio varieties, including Tardivo.
