Puntarelle is a member of the chicory family, and its bitter leaves and crisp centre are highly prized in Italy. It’s in season from November to February, so if you see one, snap it up! Here it’s served in the classic Roman style, dressed with a robust anchovy sauce. If you can’t find puntarelle, use another bitter leaf such as chicory, or substitute Tenderstem broccoli - the result will be different, but still delicious.
