You're Burning Your Olive Oil
You should never use expensive olive oil to cook something on high heat in a pan. The sugars and tannins in the oil will burn before you can even create a sear on whatever you're trying to cook. Do yourself a huge favor and just use a neutral oil if you're cooking on high heat.

There are literally dozens of different uses for muffin tins, loaf trays, bundt cake molds, and so on and so forth. You can make savory dishes, roast nuts, dry fruit, and keep individual ingredients warm unlike any other common kitchen tool.
