What's the difference between the cheaper olive oil and extra virgin olive oil?
@Maver1ck : Beware. "Extra virgin" is not a protected label in the US like it is elsewhere, so they can legally call anything extra virgin. (The official designations in the US ate something weird like "fancy olive oil" and date from like the 1910s when I guess that sounded less laughable.).
I wouldn't fry chicken with it. Extra virgin olive oil has a very low smoke point and you'll end up setting off your smoke detector and opening the windows and cursing your burned, blackened chicken. Some refined olive oils are supposed to have a higher smoke point but I still wouldn't try it. You can sauté with it though.
IMO olive oil is better cold anyway. On a salad or drizzled over veggies or on toast. It's got a strong flavor so don't cook or bake with it unless you want olive oil flavor.
FYI the Central Market olive oil from Spain that they sell in metal jugs at HEB is good and not exorbitantly priced.
