Bubalus Bubalis & How He Got to Naples
is Yiddish for "buffaloes that stutter." No,
actually, it's the Linnaean binomial taxonomy —meaning
that the genus is bubalus
and the species B.
bubalis— for what is generally called the water
buffalo. It is also called the domestic Asian water
buffalo and in Italy is now also termed the Mediterranean
Italian buffalo. It is a bovine, but, in spite of the term
"buffalo," is a separate genus from other bovines that may
also be popularly called "buffalo" in some parts of the
world—the North American bison, for example. (I mean,
would you even go out
with a woman called a "bubalus gal"?)
Most of the world's 160 million water buffaloes are in Asia where they are used as draft, meat and dairy animals; the dung is also used as fertilizer and fuel. In some parts of Asia, they have buffalo races and buffalo fights, and some cultures even have sacred water buffaloes. In southern Italy—primarily Campania—however, the many thousands of female water buffaloes serve a much loftier goal—producing milk to make mozzarella cheese. Italian use of the term "buffalo" reflects that, and the feminine form, bufala, has almost become generic. The male animal, bufalo, serves primarily to keep the female happy, and many of us know what that is like. Finally, the female form, bufala, may be used to mean "nonsense" or "rubbish," in the way that speakers of English use the term "baloney," which may or may not have to do with the city, Bologna. (More on that at this link.)
How did bubalus bubalis get to Naples? Some sources say that the Goths brought them from the north during the invasions following the fall of the Roman empire. (Those sources don't explain how northern Europeans got Asian water buffaloes in the first place.) Also, say some, perhaps the Crusaders brought them back from the Middle East. (That is unlikely since the animals were in Italy before the Crusades.) The chronology of the domestication of the animal speaks for itself. The Asian water buffalo is a domesticated variation of the Bubalus arnee, the wild buffalo of the Indus valley, where they were first tamed for agriculture before 2500 B.C.; thus, they were present in the famous Harappa Indus valley civilization of the Indian subcontinent and then spread west shortly thereafter to Mesopotamia during the period of the Akkadian dynasty. In light of that, the most commonly accepted explanation for their presence in Italy is relatively straightforward: Arab/Islamic colonizers and traders found the buffalo as they moved east in the 600s and then introduced it in the west in North Africa and Sicily. From there the animals spread to the Italian mainland at various Arab enclaves in the south. The Arabs brought with them the art of making dairy products from buffalo milk and imparted that art to the natives (captured Benedictine monks, according to some sources). The tradition of making mozzarella became firmly entrenched and stayed even after the Arabs lost their footholds on the southern mainland and eventually lost Sicily, itself, to the Normans in the 1000s. Sources document the presence of producers of mozzarella in the area of Aversa, the initial Norman holding in the south, as early as the 11th century. After that, the tradition of mozzarella in Campania is solidly established.
There is some confusion in distinguishing mozzarella and fior di latte, a cheese made from cow's milk. Mozzarella is made only from buffalo milk. That confusion exists elsewhere, but not in Campania or anywhere in southern Italy. That is, they—who know the difference—might try to sell you a pizza with cheese made from pasteurized cow's milk, but they know they shouldn't. A real Neapolitan pizza has to be made with real Campanian mozzarella as defined by the law governing foodstuffs of Denominazione di origine controllata (DOC)—Protected Geographical Status. There is, in fact, a consortium responsible for the "protection, surveillance, promotion and marketing" of the Buffalo Cheese of Campania.
Finally, although I have used it here, the term "mozzarella cheese" makes no sense in Italian. You either want mozzarella or cheese. It can't be both. That would be as confusing as, well, bubalus bubalis, and we don't want that. Also, the term mozzarella comes from the verb mozzare, meaning "to break off" and refers to a step in the shaping of the finished product. It does NOT mean "cut" and it's not cheese, so you can forget that joke you've just been dying to blurt out, you vulgarian, you.
