Olive Oil
Extra-virgin olive oil, with its intense fruity taste and low smoke point of 250, should be added for flavor after cooking a dish, mixed into dressings or drizzled on bread. Use plain olive oil (smoke point 410) for cooking.
Grape-Seed Oil
This clear oil is a good base to which to add flavored infusions. A 420 smoke point makes grape-seed oil great for cooking over high heat. It emulsifies well, so it is easy to whip into mayonnaise. But don't use it in dressings; it has no flavor.
Tea Oil
Tea seeds are cold-pressed to produce this aromatic sweet oil, which can be used for sauteing or tossed into pastas or salads. Tea oil has a high flash point, which allows for cooking to 485 without burning or smoking.
Avocado Oil
This oil from Mexico and New Zealand has an exceptionally high smoke point of 500, which makes it good for baking, sauteing and frying. When infused with other flavors, it makes good salad dressings and marinades.
