We brought a bottle of the lemon liquor back from Liguria this trip. I had been calling it Limoncello but today I noticed the bottle said Limoncino. After half-hearted googling, it seems in the north they call it Limoncino, particularly around the Cinque Terre, and in the south Limoncello. Yet another reason to get to the Amalfi Coast someday! Then I ran across a producer in Ventura County.
