A distinctively nutty-flavored oil extracted from walnut meats. Walnut oil is expensive and can be found in supermarkets, gourmet food stores and natural food stores. Store in a cool, dark place for up to 3 months; refrigerate to prevent rancidity. The French term for walnut oil is huile de noix. See also fats and oils.
