   • 2011, Robin Raisfeld & Rob Patronite, Bowled Over, New York Magazine:

     The pièce de résistance, though, is a dried tubular pasta called anelloni, a fashion-forward shape that dares to wear its sauce-clinging ridges on the inside of the loop instead of on the outside[1]

2. A type of pasta developed to investigate ring-shaped polymers.[2]
   • 2014, Davide Michieletto & Matthew S. Turner, A taste for anelloni, Physics World (IOP), pages 28-31:

     So we decided to create our own "ring spaghetti" — or "anelloni" as we've decided to call it (anello in Italian meaning "ring").[2]
