Distinctly and intensely flavoured with the limone dfusato dio amalfi, this is indeed a national treasure and as such has been designated as a Slow Food Presidia (Biodivesity). Does it make it taste any better? For me, definitely. Because I know the protection afforded to these lemons by the Foundation means that they will be available for many years of enjoyment in the future.
The chinotto is also very tasty.
