Olive oil is a liquid fat obtained from olives, the fruit of Olea europaea; family Oleaceae, a traditional tree crop of the Mediterranean Basin. One of the three core food plants in Mediterranean cuisine, the other two are wheat and grapes.
All olives left on the tree will eventually ripen to black. Olives can be pickled at any stage of ripeness. “Green ripe olives” are picked at a certain stage of development, when the juice inside turns from clear to milky.
