Lila,
I wrote a piece on
pesto alla genovese with illustrations here:
http://lthforum.com/bb/viewtopic.php?p=41428#p41428In the picture, I did not use trofie but certainly do on occasion; my son and I make them by hand sometimes.
The dish is most decidedly not Roman but typically, quintessentially even, Ligurian, and closely associated with the cuisine of Genova, though it is now enjoyed throughout Italy to a degree as part of the national or supraregional cuisine.
One might think of the potatoes as a stretching element -- in a sense they are -- but as I note in the piece linked to above, they also add a wonderful textural complexity to the dish...
I think maybe I'll post something involving potatoes I wrote and posted elsewhere some years back...
I've discussed the Italian use of potatoes in traditional cooking in at least two of the Oxford Symposium articles that I've published, the one in the 2005 Proceedings, the other in the 2007 Proceedings... More will appear in a forthcoming book...
