I know there are other things to do with rapini but I am stuck in a happy rut. I always eat it exactly the same way. Rapini also called broccoli rabe looks like a leafy miniature broccoli and has a slight bitterness to it that marries well with the richness of Italian sausage. Toss that combination with a little onion, garlic, chili flakes and pasta and you're in business.
Broccoli rabe or rapini was something I ate in Italy, there it was blanched and then sauted in olive oil with garlic. Only in Italy it was called broccoli rape pronounced "rah-pay". But I imagine the "rape" name has not helped it much in the popularity department in the English speaking world. If you look it up in the dictionary it turns out to have even more names – rapa, raab, rappone (for big bunches I guess) Italian turnip, taitcat and turnip broccoli. In Italian rapa means turnip and broccoli means broccoli.
As for the identity crisis – am I a turnip or am I broccoli? It is a relative of the turnip and yet looks more like broccoli. As far as the names goes, I think I'll stick with rapini.
