Cooking with olive oil is like cooking with wine. Never use a wine or olive oil that does not taste good to you. An inferior one will leave an aftertaste. If you do the taste test and compare
the "pure" to the "extra-virgin" and the you'll understand the difference.

When cooking with olive oil, save your extra-
virgin oils for salads, dressings, and vinaigrettes. You can also drizzle it over slices of crusty bread
or onto open-face sandwiches. Use it on a baked potato or add it to mashed potatoes instead of butter. Extra virgin olive oil tastes great on
cooked vegetables or brushed onto fish or meat before serving.
