Walnut oil

Walnuts and their oils are excellent sources of omega-3 fatty acids. Most of the research on the health benefits of walnuts has focused on consumption of the nut itself, although interest in walnut oil has grown over the last decade.Walnut oil has a rich, nutty flavor that is perfect for salad dressings, to flavor fish and steaks, to toss with pasta, and to jazz up desserts. Walnut oil is best used uncooked or in cold sauces because when it is heated, it can become slightly bitter. This flavor, however, can be a pleasant taste when experienced in moderation.
