Extra-virgin olive oil is considered unrefined and of the highest quality of all the grades of olive oil.

Olive oil can appear cloudy for many reasons, including it is an unfiltered olive  oil (which just means the sediment and pulp was not removed) to chilling (cold olive oil can take on a cloudy appearance). The sediment in unfiltered olive oils is nothing more than pieces of olive that actually add flavor to the oil. To clear olive oil that has become cloudy because of temperature, just leave out at room temperature. The saturated fat that congealed in the cold will settle naturally.

Most people warn of the lower smoke point of olive oil compared to peanut or corn oil, which are more often used for frying. Once oil reaches its smoke point, it can release toxic compounds that no one wants to eat. However, refined olive oil has a smoke point of 486 degrees F, making it suitable for deep frying — but we wouldn’t recommend using extra-virgin olive oil, which has a lower smoke point.
