Radicchio is one of those interesting vegetables that so many people don't know what to do with. Most of us are introduced to it in a salad where it is mixed in raw to add some color to the rest of the greens and yet that is the worst way to eat it.
To me radicchio is the Jekyell and Hyde of vegetables; served raw it's bitter and practically inedible but slow grilled or baked in the oven with olive oil and salt it becomes a crisp and almost buttery sweet treat. Such a difference adding heat makes!
I reach for radicchio when I find myself tiring of a constant stream of green vegetables; its slight peppery flavor breaks the monotony. But be sure to buy fresh heads (firm when lightly squeezed and crisp looking leaves) or it will continue to taste bitter despite the baking or grilling.
I like to make grilled radicchio along with a mix of other vegetables, such as asparagus or green beans and then serve them all on a platter. Adding some minced rosemary when baking or grilling also works well. Chopped parsley or mint are wonderful garnishes too.
