Looking for a specific type of pasta to go with pesto I was half-listening to a cooking show on TV the other day and heard that pesto sauce should be served with a type of pasta that's made just for pesto. The pasta itself has some potato in it (or was it the dish?) and it's pronounced pro-fee? I have no idea and I around at my local market, and they all just suggested regular spaghetti.

I might have heard wrong from the television, but does anyone know what this pasta might actually be?
Trofie.

Pesto originated from Liguria (the region). If you google liguria pesto potato you get recipe's like this Martha Stewart.  Though I'm by no means endorsing her recipe. 

The pasta itself is durum wheat flower, the dish you describe is from Genova (in Liguria) and has potato in it.
