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?
