In autumn and winter, here in Italy, we use to eat a certain kind of
vegetable called "Radicchio". This is a link where you can see the photo:

The taste is a little bitter, but we like it for this reason. We mix it with
green salad (like lettuce, for example), or we make a very very good
seasoning for pasta (you mix, for example radicchio with sausages). For
these recipes it is better using "Radicchio di Chioggia or Verona, which is
ball shaped (see the photo in the link). The other kind "Radicchio di
Treviso" is long shaped and is good for BBQing.
Today or tomorrow, I would like to make Ravioli (handmade) filled with
ricotta and radicchio (Gnam Gnam).
I would like to know if you have Radicchio in Usa and other country of the
world.
