Ingredients Guide

Hazelnut oil, with its delicate nutty flavour and aroma, is a versatile ingredient that elevates both sweet and savoury dishes. This comprehensive guide explores the fascinating history, diverse applications, and health benefits of hazelnut oil, providing you with all the knowledge you need to incorporate this delightful oil into your cooking repertoire.

1. History of Hazelnut Oil:

Hazelnut oil's history is intertwined with the hazelnut itself. The hazelnut tree (Corylus avellana) has been cultivated for thousands of years, originating in Asia Minor, the region encompassing modern-day Turkey and surrounding areas. From there, hazelnuts and their oil spread throughout Europe and eventually the rest of the world. Evidence suggests that the ancient Greeks and Romans were familiar with hazelnuts, using them for both food and medicinal purposes. Hazelnut oil, however, was likely a byproduct of hazelnut cultivation, pressed to extract the valuable oil. Its use in cooking has evolved over centuries, with its popularity waxing and waning depending on availability and cultural preferences. Today, it enjoys a well-deserved reputation as a gourmet oil, prized for its flavour and versatility.

2. Cooking Techniques:

Hazelnut oil is a delicate oil best used in ways that preserve its flavour and aroma. It has a relatively low smoke point compared to some other oils, making it unsuitable for high-heat cooking methods like deep frying. Instead, it shines in:

• How to cook hazelnut oil (general overview): Hazelnut oil is best used as a finishing oil or as a base for dressings and sauces. Its flavour is enhanced by gentle heating. It is best to add the oil towards the end of cooking or to use it as a drizzle to finish off a dish.
• How to prepare hazelnut oil for cooking: No special preparation is needed. Simply measure the desired amount.
• How to grill hazelnut oil: Hazelnut oil is not ideal for grilling, as it can burn and become bitter. Instead, use a higher smoke point oil like sunflower oil or avocado oil.
• How to bake hazelnut oil: Hazelnut oil can be used in baking, but it's more cost-effective to use a neutral-flavoured oil like rapeseed oil, which doesn't detract from the overall flavour profile. However, it is delicious in smaller quantities. Use it in cakes, biscuits, or muffins for a subtly nutty flavour.
• How to sauté hazelnut oil: Sautéing should be done at low to medium heat. Add ingredients to the pan and sauté quickly. Be careful not to let it smoke.

3. Ingredient Preparation (Not Applicable):

Hazelnut oil is pre-prepared; therefore, no ingredient preparation steps are required.

4. Storage:

Proper storage is crucial to maintain the quality and extend the shelf life of hazelnut oil.

• How to store hazelnut oil (short-term and long-term): Store hazelnut oil in a cool, dark place, away from direct sunlight and heat. A pantry or cupboard is ideal. After opening, keep the bottle tightly sealed to minimise air exposure. Refrigeration can help extend its shelf life, especially for longer-term storage, but it may cause the oil to cloud. This is normal, and the cloudiness will disappear when the oil returns to room temperature.
• How long does hazelnut oil typically last under different storage conditions? Unopened, hazelnut oil can last for 12-18 months, stored correctly. Once opened, it is best to use it within 6 months. Refrigeration can help extend its life by a few more months.

5. Substitutions:

If hazelnut oil is unavailable or an allergy is present, consider these substitutes:

• Good substitutes for hazelnut oil:
  • Walnut oil: Offers a similar nutty flavour profile, although more robust.
  • Almond oil: A milder nutty flavour and aroma, but also has an excellent taste.
  • Macadamia Nut Oil: Similar flavour, and can be used in small quantities to replace hazelnut oil.
  • Avocado oil: A neutral-flavoured oil that will not impart a nutty taste but is suitable for cooking and contains healthy fats.
  • Sunflower oil: Another neutral-flavoured oil that can be used for cooking.
