Which brand of olive oil do you use?
I have no idea which ones are good. If I'm shopping for one, I, of course, get one that's made in Italy but other than that I don't know anything about olive oils.
Is extra virgin better than just regular?
The one I've been using is "Olio extra vergine di Oliva" by CUSCUNA. It's from Sicily. My mom bought quite a few so she gave me 2 bottles.
