Giants in my garden

Now I'm going to speak about one of our typical
fruits...

Amalfi is renowned for its outstanding lemon variety called Stufato, but there also grows another kind of lemon which isn't as famous as Stufato.
These lemons, whose name is unknown to me even after loads of researches on the web, have an odd feature which makes them really different from the Stufato, indeed their size is very large as you can understand by looking at their pictures.
One of these lemons can reach the extraordinary weight of 1.5 kg, I'm not teasing you ! trust me.
For example the one in the pictures weights about 1.1kg.
Besides their size, other characteristics are: a strong bitter taste and a very rough skin.

Unlike Stufato, you can't use this type of lemons for the flavored Limoncello and to tell the truth I don't know any recipe for using them, some say that you can serve them seasoned with oil and oregano like a "lemon salad" or you can dust some sugar over the cloves.
Where did I take those pictures? try to guess....
I took them in my garden though I don't live in Amalfi but in Naples !
My grandfather planted them many years ago, hopefully to yield another kind of lemon sometimes the destiny of the plants, like the people's, is unpredictable :)
