Olive Oil
Description
Olive oil is a liquid fat obtained from olives, the fruit of Olea europaea; it is commonly used in cooking, whether for frying or as a salad dressing. It is also used in cosmetics, pharmaceuticals, and soaps, and as a fuel for traditional oil lamps. Olive oil is regarded as a staple in the Mediterranean diet and has been of culinary and cultural significance for thousands of years. Olive oil varies in color from clear yellow to golden; some varieties are even green. The taste can vary from delicate and mellow to strong and peppery, which is a result of the olives' variety, ripeness, and extraction process.
Common uses
Olive oil is widely used as a cooking oil, for frying foods, as a salad dressing, and for drizzling over various dishes to add flavor. It is also used as a base in marinades and sauces, and for conserving food. In non-culinary applications, olive oil is used in natural skincare products, soaps, and as a traditional fuel for oil lamps in some cultures.
