Step by step

Arrange the radicchio neatly in an oiled frying pan which has a lid

Tips
Radicchio can be stored, having been cleaned and sealed in a plastic bag or wrapped in a kitchen towel, for a week. Furthermore, when you buy them choose those that are frizzy and slightly opened, with no leaves damaged or yellowed.
Trivia
There are many varieties of radicchio: the ‘red’ ones have dark red leaves and bigger white ribs such as Rosso di Treviso, Verona Red and Red Chioggia; variegated ones have yellow and green flecks, such as the Variegated Castelfranco and Chioggia; finally there are the completely white ones, such as Radicchio di Luisa.
