Radicchio is a chicory very specific to certain areas of northern Italy, especially Veneto. There are a few varieties, but Chioggia (the round kind) and Treviso (the elongated kind) are the most common. I have only ever seen Treviso in Sydney, so that's what I have used for this recipe, but the round variety works just as well. It is a bit bitter, but I love it… I mean, look at that color! So pretty! It can be eaten both raw, in salads, or cooked (the way I like it the most).
Radicchio is often not the first choice when it comes to kids, as many of them do not like its bitterness, but I find that when it is cooked and mixed with a little cream and Parmigiano-Reggiano, it tastes delicious and not so bitter any more.
