It is described somwhere because I red,it,but can't pinpoint.
Yet Sicilian figs are very easy to distinguish because they have this unique appeareance.
Whether they are Black,Gray,red or white ,they all have the same shape and interior texture.
As a Matter of fact Sal Corleone is a plant from this Family,that originated in the comune of Corleone.
That is why it is called Sal Corleone,yet it is a traditional Sicilian fig too.
The taste ,and flavor,of all this group of fig is basically very close to each other,just like Col de Dame,of all color have basically the super good taste and flavor ,that separates them from all other cultivars.
This is my own observation from experience and if you want to take it as true ,then do ,if you think that is not true,then I will not objiect to your conclusion.
