So famous, so perfect, so consistent! What can we tell you about Parmigiano Reggiano that you don't already know. The cows whose milk constitute this cheese are virtually hand-fed specially-guarded secret salads of grasses that produce a magnificent, complex flavor. A barrage of sweet, salt, spice, and nuttiness simultaneously fill your mouth: that butter, that little crunch, that caramel finish! it's the same welcome visit from that favorite old friend every time. Aged two years to absolute perfection.
