As with other mozzarellas, Burrata owes its existence to the water buffalo, a large beast that was brought to Italy from its native Asia sometime in the 1400s. Water buffalo milk is richer and higher in protein than that of cows, yielding 1.6 times more cheese. It also lacks the yellow pigment carotene found in cow’s milk, so mozzarella di bufala is pure white. Although mozzarella was originally made with the milk of water buffaloes, and the best still is (in Italy, the legal name for cow’s-milk "mozzarella," is fior di latte), almost all American mozzarella is made from cow’s milk.
Burrata originated from a small area of Apulia region, called Murgia. First produced around 1920 on the Bianchini farm in the town of Andria, (about 2/3 of the way up from Italy's heel to the spur of Apulia). In the 1950s, it became more widely available after a few of the local cheese factories - notably Chieppa - began producing it. It is generally suspected that factories were interested in it because it was a way to utilize the ritagli ("scraps" or "rags") of mozzarella. Established as an artisanal cheese, Burrata maintained its premium-product status even after it began to be made in a number of factories from Andria, Bari, Gioia del Colle, Modugno, all the way to Martina Franca, an eighty-mile stretch of Puglia. Notably, only in recent years has it traveled outside of its native Apulia.
