This simple dish is known in Sicily as Pasta alla Milanese, or "pasta for the people of Milan". That's because Milan is well inland, so Sicilians who went north for work could not get the fresh fish that features so prominently in Sicilian cuisine, so they had to used preserved sardines with their pasta.

This is a very simple dish, but the flavor is unique and the people who tried it all liked it. I suppose it helps the poor homesick Sicilians of Milan!
