Preserving food in olive oil goes back to ancient times. The practice is believed to have originated in countries around the Mediterranean and Northern Africa where one of the most natural ways to preserve food was and still is with olive oil.
Due to its natural properties which prevent spoilage by providing a seal which delays oxidation and molding, olive oil is particularly well suited for storing herbs, fruits and vegetables.
Preserving in olive oil is an ideal method to conserve the nutritional value and flavor of fresh foods.
