Made from the whey of feta and kefalotyri and mixed with whole milk, the pleasantly tangy myzithra can be served as a soft table cheese. Greece’s best-loved grating cheese, it is more commonly left to age until it becomes rock-hard, rendering it Greece’s best-loved grating cheese (akin to ricotta salata).It is traditionally shaped into an ostrich egg-sized ball. Ours is available in this form or pre-grated. Another perfect substitute for parmesan, myzithra is fast becoming one of America’s favorite cheeses, as evidenced by its appearance for many years on the menu of the Old Spaghetti Factory. One of the restaurant chain’s perennially popular dishes, the myzithra is mixed with browned butter and served on pasta.
