Castel Franco is a type of chicory, often considered a variety of radicchio, known for its unique appearance and mild flavor. It is characterized by its round, open heads with creamy, pale yellow leaves that are speckled with red or purple spots, giving it a delicate and beautiful appearance. Sometimes referred to as "orchid lettuce" due to its colorful pattern, Castel Franco has a slightly bitter taste, less intense than other radicchio varieties, with a tender and crisp texture. It is typically used in salads to add color and a mild bitterness, but it can also be sautéed, grilled, or roasted to enhance its flavor.
