Don't confuse olive oil for cooking (commonly purchased in 3 liter tins) with extra virgin olive oil. This article is about extra virgin olive oil. EVOO is usually consumed raw, unheated, with bread, cheese, on salads - it would completely defeat the purpose of the EVOO production technique which is one of low temperture, purely mechanical extraction, to heat EVOO to high temperatures as is commonly done with lower grades of olive oil.
