Ossau-Iraty is an uncooked, pressed, semi-hard cheese made from sheep's milk from the Pyrenees mountain range. Small cheeses of this sort must mature for 60 days, while the standard-sized Ossau-Iraty matures for at least 90 days. Underneath its moldy, iron-gray rind hides an ivory-colored body that is somewhat granular and creamy in its texture and melts very easily.
