I used to cook with it too. I love olive oil. But it becomes toxic when heated. So save your really good olive oils for salads, or for drizzling over foods AFTER cooking is done.
For heating up, the best oil is coconut. It can take the heat. Get extra-virgin.
toxic? I had no idea.
Quick question: I usually brush olive oil on both sides of a thick steak, salt and pepper and then into the broiler the steak goes. The results are first rate but would the Olive oil be toxic in this instance as well?
