Kefalotyri refers to a tangy hard cheese from Greece that is made from sheep and goat's milk. Kefalotyri has a tangy flavor and a sharp aroma that is somewhat similar to Italian Pecorino, and has a pale, golden yellow color. Saltier and harder than Kasseri cheese, Kefalotyri is generally served grated over cooked dishes. If not available, Kefalotyri can be subsituted by Parmesan or Romano cheese
