This allows the full flavor and aroma of the olive oil to shine through, and helps to preserve its nutritional benefits. If you need to cook with olive oil, it is better to use a more robust variety, such as pure or light olive oil, which has a higher smoke point and can withstand higher temperatures. By using the right olive oil for the job, you can ensure that your dishes turn out flavorful and healthy, and that you get the most out of your olive oil.
What is the difference between extra virgin and regular olive oil?
The main difference between extra virgin olive oil (EVOO) and regular olive oil is the level of acidity and the production process. EVOO is made from the first pressing of olives and has a lower acidity level, typically less than 0.8%. Regular olive oil, on the other hand, can be a blend of different oils and has a higher acidity level. EVOO is also considered to be of higher quality and has a more delicate flavor and aroma. The production process for EVOO is also more rigorous, with stricter standards for harvesting, pressing, and bottling.
In terms of usage, EVOO is best used as a finishing oil, adding it to dishes just before serving to preserve its flavor and aroma.
