Radicchio chicory is an acquired taste. We are still learning to appreciate it, and this recipe has been, so far, the most palatable radicchio recipe to date, to us newcomers. Will definitely make it again.
I did make a few changes to the cooking steps:
1. I knew that the final result would not be room temperature if I put the pasta in the refrigerator. On the contrary: I used the cooking water to heat up the mixing bowl into which I then put the pasta.
2. I knew the radicchio would never even remotely "wilt" if I tossed it in off the heat. I kept it on very low heat (60°c) just long enough for it to get warm.
3. I used whole wheat pasta, which is also an acquired taste, it worked wonderfully.
The dish tasted like "want more", and the blend of pasta, semi-raw radicchio, lemony herbs and a touch of Gorgonzolla made it a perfect, refreshing, 1 pot meal.
