Casciotta d'Urbino
Casciotta d'Urbino or Casciotta di Urbino is a type of caciotta cheese made in the province of Pesaro and Urbino, in the Marche region of Italy. This cheese is generally made of between 70 and 80% sheep's milk with 20–30% cow's milk. Local legend has it that the name came about from a mis-pronunciation of "caciotta" by a local civil servant, some say it is derived from the local dialect.
