So as I understand it, virgin olive oil is made from cold pressing olives.
If I fry or roast stuff using virgin olive oil, did I just waste my money?

(I’m going to write with confidence, but I’m not an expert, just grew up around chefs. Please feel free and welcome to fact check me.)
Yeah, EVOO is made by cold-pressing the olives, and regular olive oil by hot pressing. Cold pressing releases less oil and also several tasty compounds that come along for the ride. Hot pressing releases more oil but also other compounds that don’t taste as nice, so generally regular olive oil will then be refined, removing most of the compounds that give it flavor. If you compare, you’ll find that real EVOO[1] tastes distinctly olive-y, and regular olive oil has very little flavor at all.
When it comes to cooking, traditional advice is not to cook with EVOO because it’s got a low-ish smoke point[2], whereas regular olive oil (which has been refined) will have a higher smoke point. EVOO’s smoke point isn’t actually that low, but I generally avoid high temp cooking with it anyway in favor of things like avocado oil (my personal go-to), peanut oil, or vegetable oil which are very tolerant of high temperatures. You absolutely can cook with EVOO though if you only want to keep one kind of oil around the house or something.
To clarify: heating up EVOO and cooking with it is fine as long as you don’t smoke it. It won’t make it any less extra-virgin or anything: to get those less good-tasting things into your oil, you need to heat up the olives themselves.
So are you wasting money if you do cook with it? Maybe.
Do you want what you’re cooking to taste like olive oil? If you do, cook with it! Real[1:1] EVOO has a distinct taste that won’t go away when heated (unless you smoke it). It’s great for making stuff like olive oil cake! If you don’t care or don’t want that flavor in whatever you’re cooking, then yeah it’s probably a waste of money. There are many less expensive oils that will work well and have neutral flavors or different flavors that you might prefer, including regular olive oil.
All of this is avoiding the issue of regular olive oil being passed off as EVOO when it actually isn’t. If you want something interesting to read about this evening, try researching olive oil fraud. ↩︎ ↩︎
In case you don’t know, smoke point is the temperature where an oil starts to burn, which tastes bad, isn’t very healthy, and will probably set off your smoke alarm. ↩︎
Thanks for the in-depth answer!
Generally I keep two oils around the house. High quality, EVOO produced in my area of the world. And canola oil that I buy by the gallon and use for anything where I want more than just a little oil.
I just read up on olive oil fraud, interesting! I took some advice on testing it, and tried eating (drinking?) a spoonful. Even though I felt like a weirdo, I’m pretty sure mine is the real deal.
I guess I’ll continue using it as I have been, as it seems heating it doesn’t turn it into regular olive oil so long as you don’t burn it. Thanks!
Glad you found it useful! When I started writing it nobody else had answered and by the time I posted it a bunch of other people had replied (that’s what I get for walking away while writing it).
