Radicchio looks like red cabbage. It's mainly used in salads, and its bitter flavour contrasts well with milder leaves such as rocket. The leaves themselves are tender but the heads are sturdy enough to be cut and grilled.
How to Select
Look for crisp leaves with no wilting or browning.
How to Store
Radicchio will last for around a week In a perforated bag in the fridge.
How to Prepare
Wash, then break the leaves off the base and leave whole or tear or shred, as desired. If grilling, wash and cut into wedges.
