Extra virgin olive oil
"Nobody should have to face the olive oil aisle alone, so here's my cheat sheet, collected from various sources including the International Olive Oil Council:
* Extra virgin olive oil comes from the first pressing of the fruit of the olive tree, using solely mechanical or other physical means in conditions, particularly thermal conditions, which do not alter the oil in any way. It has not undergone any treatment other than washing, decanting, centrifuging and filtering. It must have less than 1% acidity. Most expensive; best for salads and drizzling on finished dishes.
* Virgin olive oil, made in the same way as extra virgin, has an acidity less than 2%, and has a good taste. There can be no refined oil in virgin olive oil. Good for cooking, and fine for salad dressings, in a pinch.
* Olive oil is a blend of virgin oil and refined virgin oil, containing at most 1% acidity. Mild flavor; for cooking only.
* Refined olive oil, also called pure oil, is a lesser grade than virgin. No real good use for this. [The Perfect Pantry: Extra virgin olive oil]
Hmmmm. Rachael Ray cooks everything with EVOO. I always just figured "extra virgin" was a shortcut to picking the best oil. . . except maybe not for cooking? The above writer (and the International Olive Oil Council) says perhaps not. . .
