I ‘ve tasted olive oil when I had the chance to travel to other countries, except it barely resembled the olive oil I know. It tasted bad, and it didn’t even look like the real thing. This could have only been fake or otherwise diluted olive oil. I doubt any kind of olive tree produces that kind of oil anyway.
By the way, I noticed from my time in some European cities, that olive oil is sold for a very high price. I understand that imported goods are expensive, but the prices I saw at super markets were just ridiculous ( and it’s possible even that was for ‘fake’ olive oil).
