Spaghetti With Pesto Trapanese

You are all familiar with the traditional pesto (basil pine nuts, olive oil, Parmesan and garlic) from Genoa but in Sicily (in Trapani, specifically) they add a twist: blanched almonds, tomatoes and pecorino (or ricotta salata) and call it “pasta cull’agghia” (pasta with garlic). This makes the sauce very rich and crunchy. While the Trapani version is the most popular, there are many different variations to this pesto, depending on where you are in Sicily. In the Eolian islands they add salt packed capers (their specialty) and pistachios. In other places, they roast the tomatoes (and or add sun dried tomatoes) to provide further richness. Some others roast the almonds (the purist would cringe!), and yet some others add bread crumbs. Finally some like it hot and add chili pepper.
Either way you make it, try this pesto with "busiati"...if you feel like making home made pasta. It is a very simple flour and water dough that is quickly rolled around the “busu” (or knitting needle) to obtain a sort of “fusillo” (twisted long pasta).

NOTE: the writer uses this pesto as a dipping sauce for fried fish.
