What is a primary characteristic of culinary walnut oil?
FAQ
Frequently Asked Questions
Yes, but it is best used for low-heat cooking or as a finishing oil drizzled over dishes after cooking, as it has a low smoke point and heat can destroy its delicate flavour.
It has a rich, nutty flavour with slightly bitter undertones, reminiscent of walnuts. The flavour intensity varies depending on whether it is refined or cold-pressed.
Yes, it is a good source of omega-3 fatty acids (ALA) and antioxidants. Like all oils, it should be consumed in moderation due to its high calorie content.
Wood finishing walnut oil is often polymerised (heated) or has driers added to help it cure and harden on the wood surface. Culinary walnut oil is food-grade and never treated with such additives.
