I use olive oil in most everything that has "Oil" in the ingredient list also, It does not only have to do with the flavor, it also has to do with the health aspects and behavior of the oil compared to others.
Oils and fats (lipids) are needed in our diets, they are beneficial to our health and well being. Olive oil is one of the few oils that has more benefits to our health than most any other lipid and it is still affordable for every day use unlike most avocado, walnut, hazelnut. and other healthy oils.
I reserve the extra virgin olive oil for use as a condiment or flavoring component after an item is cooked. I use regular olive oil if it is going to be seeing any heat increases or decreases.
I do several prepared cold salads and meat marinades with olive oil, an extra virgin oil will coagulate at refrigerator temperatures and look quite ugly and nasty! sort of like a partially set Jello, where the regular olive oils stay fluid at temps around 34-38 degrees and they are more visually appealing than EVOO.
I know someone is going to mention that canola oil is supposed to be good for us, but go ahead and stick you finger in some canola oil and taste the stuff! it tastes horrible, and it coats your tongue and leaves a foul aftertaste
I hate canola oil! I will not even use it in a deep-fryer because it does not brown foods very well, and it sticks to foods too much. for frying I prefer a solid shortening with a large animal fat percentage. If you are worried about your health, you should not be eating deep-fried foods anyways.
