A Journey Through Time: The History of Hazelnuts
Hazelnuts, also known as cobnuts or filberts, boast a rich and ancient history. Evidence suggests that humans have enjoyed these nuts since the Mesolithic period, thousands of years ago! They originated in Anatolia, in modern-day Turkey, and gradually spread across Europe and Asia.
The Romans cultivated hazelnuts extensively, recognizing their nutritional value and versatility. Hazelnuts became a staple food source in many cultures throughout the Middle Ages. They even became a symbol of fertility and good luck, adding a touch of folklore to their historical significance.
Today, Turkey remains a leading producer of hazelnuts, followed by Italy, the United States, and Spain. From ancient times to modern-day kitchens, hazelnuts have remained a popular choice.
Unlocking the Flavour: Cooking Techniques and Preparations
Hazelnuts bring a unique flavour and satisfying crunch to both sweet and savoury dishes. Here’s how to make the most of these versatile nuts.
General Overview of Cooking with Hazelnuts
Hazelnuts can be eaten raw, but roasting them unlocks their full flavour potential and brings out their delicious aroma. They can also be used in a variety of cooking methods like baking, sautéing, and incorporating into sauces and spreads.
Preparing Hazelnuts for Cooking
Before you can begin cooking with hazelnuts, they generally need to be shelled. You can save time and effort by buying pre-shelled hazelnuts. If you’re shelling them yourself, use a nutcracker or place the nut in a folded towel and gently tap it with a heavy object like a rolling pin.
After shelling, you may also choose to remove the thin, papery brown skin. While this isn’t mandatory, removing the skin can improve the texture and flavour.
Roasting Hazelnuts: The Secret to Enhanced Flavor
Roasting hazelnuts is a simple process that significantly enhances their flavour. Here’s how to do it:
- Preheat: Preheat your oven to 175°C (350°F).
- Spread: Spread the hazelnuts on a baking tray in a single layer.
- Roast: Roast for 10-15 minutes, or until the skins begin to split and the nuts become fragrant. Keep a close eye on them to prevent burning.
- Cool and Rub: Once roasted, let them cool slightly before rubbing them in a clean kitchen towel to remove the skins, if desired.
Other Cooking Methods: Grilling, Baking, and Sautéing
While roasting is the most common method, hazelnuts can also be used in other ways:
- Grilling: Hazelnuts aren’t typically grilled on their own, but they add a delightful crunch to grilled dishes. For example, include chopped hazelnuts in a vegetable skewer, or sprinkle roasted hazelnuts over grilled meats or vegetables.
- Baking: Hazelnuts are a fantastic addition to baked goods. Add them whole, chopped, or ground into flour. They’re a great addition to cakes, cookies, muffins, and breads. Try them in brownies or shortbread recipes!
- Sautéing: Sauté hazelnuts in butter or oil over medium heat for a few minutes, until lightly toasted. This adds a lovely touch to salads or savoury dishes.
Mastering Ingredient Preparation
Proper preparation is crucial to getting the best results when cooking with hazelnuts.
How to Cut Hazelnuts
Cutting hazelnuts requires a sharp knife and a cutting board. You can chop them into varying sizes depending on the recipe: roughly chopped, finely chopped, or sliced. Be careful not to cut yourself.
How to Peel Hazelnuts
While not essential, peeling hazelnuts can improve the texture and appearance of the final dish. After roasting, place the warm nuts in a clean kitchen towel and rub vigorously to remove the thin, papery skins. For a more thorough peel, you can blanch the hazelnuts in boiling water for about a minute, then rub the skins off.
Dicing, Mincing, and Other Cuts
- Dicing: Dicing hazelnuts involves chopping them into small, evenly sized pieces. Roughly chop the nuts first, then use a rocking motion with a sharp knife to refine the size.
- Mincing: Mincing hazelnuts results in very fine pieces, almost a paste. This is usually done after chopping, further reducing the size of the hazelnuts.
Keeping it Fresh: Proper Hazelnut Storage
Proper storage is key to keeping your hazelnuts fresh and flavorful.
Storage Guidelines: Short-Term and Long-Term
- Short-term (up to 1 month): Store shelled hazelnuts in an airtight container in a cool, dark, and dry place, such as a pantry or cupboard.
- Long-term (up to 1 year): For longer storage, place shelled hazelnuts in an airtight container or freezer bag and store them in the freezer. They can also be stored in the fridge for a few months.
Shelf Life: How Long Do Hazelnuts Last?
Here’s how long you can typically expect hazelnuts to last under different storage conditions:
- Room Temperature: 1-2 weeks (shelled)
- Refrigerator: 2-3 months (shelled)
- Freezer: 6-12 months (shelled)

- Almonds: Offer a similar texture and flavour profile, especially when roasted.
- Walnuts: Have a slightly more robust flavour that works well in some recipes.
