Radicebio Salad Vicenza-style

Treviso radicchio, the most special of them all, is unfortunately seldom seen in the UK. It has long, narrow leaves and a particularly good flavour. While growing it is dug out so that it is blanched by frost and becomes exceptionally crisp. Originally a type of Venetian endive, it was cleverly developed by a Flemish botanist called Van den Boor. This delicious salad has one of those full-bodied dressings they like using in the Vicenza province. It is excellent with grilled steak.
