The Italian citron, also known as Citrus medica, is a large, fragrant citrus fruit with a thick, knobbly rind and a pale, segmented interior. Originating from the regions around Italy and the Mediterranean, its prominent cultivars include the Diamante, which is particularly praised for its thick peel and aromatic qualities. The scent profile of the Italian citron is highly aromatic; its rind releases a refreshing, zesty fragrance that combines elements of lemon with floral and slightly herbal undertones, making it distinctively rich and complex. The oil from the peel, often used in perfumery and culinary contexts, carries robust citrus notes that are clean and bright, yet sweeter and more nuanced than the typical lemon. This aroma makes it a favored ingredient in various traditional applications, from flavoring foods to serving as a key component in religious and cultural rituals.
