"Culurgiones" (in sardinian dialect) are the classic stuffed ravioli from Sardinia, but they are also well-known in the rest of Italy for their goodness and the particular filling, which is, according to the Island's areas, generally made with seasoned Sardinian pecorino cheese , or with potatoes and mint (my favorites) , served with plenty of pecorino cheese or a simple tomato sauce.
They have a crescent shape that is characterized by the closure of the edges - in Sardinian called "Sa spighitta" - because, pinching them with fingers, recalls the image of an ear of wheat (I'm not sure this is the right translation of spiga di grano)
