Olive Oil is something I hold dearest to my heart, living so close to San Francisco and being able to buy such good dipping bread!
On the night's I don't feel too guilty, I get my collection from around the world. I am particularily in to First Cold Press Extra Virgin Australian Olive Oil right now, It's very mild and slightly fruity, which is very exciting. I purchased it from Trader Joes, and it was around $8 for the 500ml bottle.
As I am sure you have heard, but it bears repeating, for dipping and salad dressing oil, you can never go wrong with any First Cold Press Extra Virgin oil, no matter what the origin. A small plug for a local supplier, Stonehouse (Stonehouse California Olive Oil Company, Extra Virgin Olive Oil and Balsamic Vinegars
) Sevillano is the best California Olive Oil i've had!
