Once they were good and browned, I set the chops aside and made two identical pan sauces in each skillet, this time with leeks, white wine, a little chicken stock, garlic, and lemon zest. This time there was a very subtle difference between the two dishes, with the olive oil one tasting ever so slightly more rounded and less acidic than the canola oil one, but I can't stress enough how minor the difference was.
If I had eaten them even five minutes apart, I would have said they were exactly the same; only a direct side-by-side comparison made it possible to detect the difference. In fact, the difference was so subtle, I can't conclude with certainty that the oil was the reason for it. It could have just as easily been due to slightly different rates of reduction or other variations that are difficult to control with total precision when making something like a pan sauce.
In short, searing in olive oil can possibly have an impact on more delicate dishes, but it's unlikely to be a major one, and in many cases may have no impact at all. For dishes like this, if olive oil is all you have, I wouldn't worry about it too much. Based on my research, cooking with olive oil using high heat isn't nearly as problematic as most of us imagine. On the health side, I was unable to find credible evidence that cooking olive oil with high heat being bad for health and, in fact, it might be one of the more stable oils for high heat cooking.
And on the taste side, its impact is minimal to none when used to sear foods that are then served with other ingredients, like a sauce. For deep frying it does make a difference in taste, so you just have to follow your preference.
Both Kenji and I have found that you can taste olive oil when using it to sweat vegetables for simple dishes like vegetable soup, but in that instance there's no high heat involved certainly the oil never gets close to its smoke point , so once again, like deep frying, it's just a question of whether you want to taste the olive oil or not. Of course olive oil is also more expensive than a lot of other oils, so that's a reason not to turn to it as often for these kinds of cooking tasks.
Interestingly, as Harold McGee found in his own taste tests , the flavor differences between high-quality and lesser oils are erased with heating, so when cooking it makes sense to reach for a cheaper bottle, at least as far as flavor is concerned.
The bottom line, though, is that if all you have on hand is olive oil, or if you want to cook with it for flavor, I see no reason to avoid it. Actively scan device characteristics for identification. Use precise geolocation data.

One quick method is to look for olive oil that is not bottled in clear glass.
This indicates the producer understands how olive oil should be properly stored because it degrades with light exposure. Next, check the harvest date found on the bottle and make sure it is within the last year. Lastly, if you have an opportunity to smell or taste the oil before buying it, Mountanos says that a good quality early harvest olive oil will be highly aromatic and complex in flavor.
Much of the literature that surrounds whether or not to cook with olive oil states that olive oil has a lower smoke point than most other oils. In addition to creating harmful compounds from quickly heating past its smoke point, we're told that heating it will destroy most of what makes olive oil healthy in the first place i.
However, scientific research has proved this false and tells us that high quality extra virgin olive oil that has not been refined or blended with other oils is, in fact, highly stable when heated. It not only has a high smoke point, but most importantly, it does not break down into harmful compounds like other oils when heated at high temperatures. Smoke point is frequently used when assessing olive oils and is the term used to describe the temperature at which an oil begins to have continuous visible smoke when heated.
The smoke point of olive oil will vary depending on the quality and freshness of the oil. Rather, she points out, smoke point "is a crude physical measurement of an oil when it starts to have visible smoke Research in more recent years has shown that smoke point does not correlate well with the changes in chemical composition of an oil during heating. The chemical changes are much more complex and depend on many variables such as the moisture, acidity, and antioxidant properties of an oil.
Some of the research Wang refers to can be found in this significant paper from , which verifies that smoke point is not necessarily the best indicator of an oil's stability when heated stability refers to how the oil breaks down due to high temperature.
