– What are the three most common misconceptions about olive oil among consumers?
– There are so many! Of course the first one that always comes to my mind is this idea that you cannot heat olive oil, meaning you can’t cook with it. So what are they doing in Greece, Italy, Spain, Tunisia, France and Turkey and all these countries, where people have been cooking with olive oil for centuries? They are some of the healthiest people in the world! Where did we get that idea that it is suddenly bad for you, when it’s just not? Any oil, any fat, once it is heated too high will begin to smoke, so it’s just a matter of heating the oil below its smoking point. The proper temperature for frying is about 180 C, but the smoking point for olive oil is about 210 C. So this idea that it creates toxins and is bad for you when you cook with it – it is just a big misconception. It’s the only oil that I use, and it’s the main oil that most Mediterranean countries use to cook with, so it’s absolutely fine.
Another thing… well, it is not a misconception so much. There is a lot of talk about olive oil being healthy, or other oils being healthy, because of the monounsaturated fats. People would talk about canola (rapeseed), corn or soy oil being healthy for instance, but it’s just processed in a very different way than olive oil. Something that a lot of consumers do not know, is how olive oil is produced: it’s really just, quite literally, the fruit juice of the crushed olive fruit. So it maintains a lot of its vitamins, natural nutrients and antioxidants. So not only is it a healthy source of monounsaturated fat, but it is also a fantastic source of antioxidants known as polyphenols as well. A lot of studies have shown these specific polyphenols have a wide range of health benefits. I wish more people knew that it is quite different from other oils in that sense.
Another thing that frustrates me is something called «the olive oil fridge test». Sometimes I’m reading articles and people still say that if you want to know that your olive oil is authentic, put it in the fridge and if it doesn’t solidify then it’s not authentic. This myth just needs to stop, there is no basis for this whatsoever! The UC Davis Olive Centre did a study revealing that olive oil is a complex profile of fatty acids and natural waxes that reacts differently to cool temperatures. Every oil will begin to become cloudy or solidify once it gets cold, however, there are so many factors that can contribute to how much an olive oil will begin to solidify. It can depend on the variety of olive that it was crushed from, on the time when the olives were harvested and how the oil was extracted, and things like that. From my own experience, I have two different varieties of extra virgin olive oil in bulk from two different regions: one will absolutely solidify in the cold, it’s very prone to becoming more solid in the winter than another variety will that remains more liquid at cooler temperatures. Both are very good quality oils, organoleptically and chemically, but they just react differently to cold. So I would really like for that myth to go away.
– What is your favorite olive oil? Does it depend on your mood or season?
I always answer that question the same way. If you asked me what my favorite wine is, it depends on what my mood is, the season, what I’m eating – am I eating fish or meat, or soup, or is it winter or summer? Everything like that matters. I do have some favorite oils that are kind of my go-to oils, the oil that you can’t go wrong with. Like Hojiblanca from Spain. It is just a fantastic variety that I think pairs well with everything. I love a good Frantoio from Tuscany, or Koroneiki from Greece – an excellent everyday oil to cook with and use for salads and dressings. For me, these are all go-to oils that I can feel confident recommending to anyone with any type of palate or preference.
– What should a good quality olive oil taste like? What advice could you give to those consumers who may be not so familiar with that flavor?
– That’s exactly the thing. I think some people think too much, or they want to see a lab report, they want to see the numbers, know what’s the acidity, the peroxides, and things like that. Those things of course are important but not everyone has access to the chemical analysis for every oil out there. So really the most important thing is to know what you are tasting. And to me, it’s quite simple: if the oil tastes good to your palate, if it has pleasant fruitiness, if it is something you enjoy tasting the flavor of, it is ok. If the oil has flavors or aromas that are unpleasant, such as rancidity, that is not a good thing. If the oil is kind of rancid, I always think it smells like a box of crayons. Oil should not smell earthy or what I call “skunky”. It’s not a pleasant smell or taste. This is a common affliction of a lot of restaurants who want to save money: they buy a high quality piece of fish, cook it just right, put it on your table and say: Yeah, now put some rancid fusty oil on it! That’s going to ruin the entire experience, you know! It is important to just look for that pleasant flavor, and if there is anything off about the aroma or the flavor of an oil – then it is just not good.
I also always encourage to look for flavors of actual fruit when smelling and tasting as oil: green apple, banana or dried fruits, or vegetal flavors such as garden tomato or tomato leaf, hickory, arugula, lettuces, or herbs such as mint, oregano – any natural flavors and aromas. Again, if you’re smelling and tasting something like dirty socks, mud or crayons – that is not a good sign.
