There are two kinds of mozzarella. Buffalo mozzarella made from the milk of water buffalo cows, like the ones on the left. Mozzarella made from the milk of plain cows is "fiore di latte". I never heard anybody in America asking for a "flower of milk" though. While you can find many good suppliers of local mozzarella or "flower of milk", all buffalo mozzarella cheese in America is imported from Italy, mainly from the Campania region. Many are even DOP, certified "mozzarella di bufala campana".
In the past few months, we sadly learned that these buffalo cows were grazing in contaminated fields in Campania, thanks to the Camorra's bad dealings. (Did you see the movie Gomorra?) The other day, a disturbing article in Corriere della Sera revealed that the Carabinieri (in the picture with the buffalo cows) found that out of 40 farms, 25 were using a drug which is illegal in Europe to make the buffalo cows produce more milk. The drug was made in Korea and imported by the Camorra, of course, from Albania and Switzerland. Now, 25 out of 40 farms, seems to me incredible news. Why doesn't anybody talk about it? Does the Camorra have a foot in the media, too? Do you know what you are eating?
