Next time you think about coating the bottom of a sauté pan using that prized stash of primo extra-virgin olive oil to impress your guests, consider this: According to Olive Garden's culinary guru, because of their low acidity, heating these oils depletes some of their prized flavor.
It makes more sense to reserve extra-virgin and premium extra-virgin olive oils for dressings, dipping and marinades, says Schweizer. Selected from the first press of the olives and unprocessed, these grades also command top dollar for a reason: They are of the highest quality and deemed to have the best taste.
Most chefs know this, but it can't hurt to repeat Schweizer's advice: "Every grade has a distinct quality and flavor, making each suitable for different uses and cooking methods."
