Walnut oil is a delicious and easy-to-use oil. In salads, walnut oil mixes very well with balsamic vinegar or red wine vinegar to create a simple but flavorful vinaigrette. Also try it with tarragon white vinegar. It is also delicious on grilled fish or meat: A dab of walnut oil is the perfect touch for enhancing flavors and easing digestion when added towards the end of your beef bourguignon or meat dishes. You can also try it in pasta with cheese. Don't hesitate to use it in cakes and baked goods, particularly with apples or pears.
