I have a confession to make: Until recently, I didn't know the difference between olive oil and extra-virgin olive oil.
But it turns out, there actually is a difference between the two — a big difference. In fact, the two types of olive oil are suited to completely different uses.
The main difference between olive oil and extra-virgin olive oil is smoke point, aka the temperature at which they burn.
Since extra-virgin oil is more expensive, you should save it for dressings, bread dipping, making hummus, and other things where you'll actually taste it.
So, there you have it: Olive oil and extra-virgin olive oil actually are different!
