Oil Advice, from anonymous
The safest way to get good-quality extra virgin olive oil is to pay up for California oil. Second is to get Spanish oil from TJ's or another trustworthy source. A good way to balance the omega-6 in olive oil is to get walnut oil, rich in omega-3's, and make a vinaigrette or similar with the two, in something like a 3 or 4 to 1 ratio, olive to walnut.
