3-B, I like every kind of pasta, but I certainly don't know the names of all of them. Our word list does already include quite a few - I remember
rigatoni was one of the "common" words missed by a lot of players in one of the puzzles we analysed after the rosette came in. And
farfalle (bowtie shaped) is there too.
But not
rotini. As you point out, 3-B, it is listed by at least one dictionary,
Webster's New Millennium, so it probably should be in our list. There's a picture below, courtesy of the Wikimedia Commons.
And, Vizzelina, there is also a ruotini pasta, which
is a wheel-shaped one - but it seems to be less common, and I can't find it in any English dictionary, so I'm not inclined to add it to the list, even if you were suggesting it, which you weren't.
So
rotini will go into our list. Buon appetito!
