Walnut oil is a user-friendly oil. In salads, walnut oil mixes very well with balsamic vinegar or red wine vinegar to create a simple but flavourful vinaigrette. It pairs well with tarragon vinegar. It is also delicious on grilled fish or meat: A dab of walnut oil is the perfect touch for enhancing flavours and easing digestion when added towards the end of your beef bourguignon or meat dishes. You can also try it in pasta with cheese. It can also be used in pastry and baked goods.
