"I'm a little obsessed with pecorino Romano because my family is from Sicily and this is what we've always used," Mirabile says. "I really don't care for any of the American produced Romano, they are just not as sharp and fragrant. Also if you're going to use a parmigiano, it must be from Parma, Italy and an authentic Parmigiano Reggiano."
Costco partners with Zanetti, Italy's largest exporter of Parmigiano Reggiano, ensuring high-quality cheese under its Kirkland Signature brand that's priced for value.
