If refrigerated, macadamia nut oil lasts for years. To make this oil, hot red chiles have been steeped in vegetable oil to release their heat and flavor. Once you discover the many uses of this tasty garlic-infused oil, you'll consider this another basic oil. It has become one of my favorite oils for saut ing when I want a mild flavor of garlic without having to mince one. Look for it at a farmers market.
Truffles are one of the most expensive foods in the world.
I buy this oil at Trader Joe's, selecting the white truffle oil for a mild flavor and the black variety for stronger flavor. These are by no means all of the specialty oils available. If you have a favorite that is not listed, I'd love to hear about it. Previous Good Taste column Carol Anderson is a free-lance writer.
