How to Blanch Hazelnuts: Unlocking Flavor and Smooth Textures
Blanching hazelnuts involves briefly boiling them in water and then shocking them in ice water to loosen their skins. This process makes them easier to peel, leading to a smoother texture and enhanced flavor for baking, snacking, or cooking. Efficient blanching prevents bitterness and creates a more enjoyable culinary experience.
The Magic of Blanching: Beyond Skin Deep
Hazelnuts, also known as filberts, are delicious and nutritious nuts often used in desserts, savory dishes, and as a healthy snack. However, the thin, papery skin surrounding a hazelnut can be bitter and detract from its overall flavor and texture. Blanching removes this skin, unlocking the nut’s full potential. It’s a simple technique that elevates your hazelnut-based creations from good to exceptional.
Why Blanch Hazelnuts? The Benefits Unveiled
Blanching hazelnuts offers a multitude of benefits, impacting both the flavor and texture of the nut:
- Removes Bitter Skins: The primary benefit is the easy removal of the bitter-tasting skin.
- Enhances Flavor: By removing the skin, the natural sweetness and nutty flavor are amplified.
- Improves Texture: Blanching results in a smoother, less grainy texture, particularly desirable in baked goods and spreads.
- Easier to Work With: Peeled hazelnuts are easier to chop, grind, or use whole in recipes.
- Visually Appealing: Peeled nuts have a more uniform and professional appearance.
The Blanching Process: A Step-by-Step Guide
Here’s a detailed breakdown of how to blanch hazelnuts effectively:
- Prepare the Hazelnuts: Spread the raw hazelnuts in a single layer on a baking sheet.
- Roasting (Optional but Recommended): Roast the hazelnuts in a preheated oven at 350°F (175°C) for 10-15 minutes. Roasting intensifies the flavor and further loosens the skins. Watch carefully to prevent burning. They are ready when fragrant.
- Boiling: Bring a pot of water to a rolling boil.
- Blanching: Add the hazelnuts to the boiling water and blanch for 2-3 minutes. The skins should start to crack.
- Ice Bath: Immediately transfer the blanched hazelnuts to a bowl of ice water to stop the cooking process.
- Peeling: Drain the hazelnuts and rub them vigorously with a clean kitchen towel or between your hands to remove the skins. If the skins are stubborn, you can rub them in a colander.
- Drying (Optional): If using the hazelnuts immediately, they are ready to go. If storing, spread them on a baking sheet and bake at a very low temperature (around 200°F or 95°C) for about 30 minutes to dry them thoroughly.
Troubleshooting and Common Mistakes
Even with a straightforward process, mistakes can happen. Here are some common pitfalls to avoid:
- Over-Blanching: Blanching for too long can make the hazelnuts mushy. Stick to the recommended time.
- Under-Blanching: If the skins don’t crack during blanching, they will be difficult to remove.
- Skipping the Ice Bath: The ice bath is crucial for stopping the cooking process and preventing the nuts from becoming soft.
- Improper Drying: Damp hazelnuts can spoil quickly. Ensure they are completely dry before storing.
- Burning During Roasting: Keep a close eye on the hazelnuts while roasting to prevent burning, which will result in a bitter taste.
Choosing the Right Hazelnuts
The quality of the hazelnuts directly impacts the outcome of the blanching process. Look for:
- Freshness: Hazelnuts should smell fresh and nutty, not rancid.
- Appearance: Avoid hazelnuts with cracked or damaged shells.
- Variety: Some varieties are easier to blanch than others. Experiment to find your preference.
Storing Blanched Hazelnuts
Proper storage is crucial to maintain the quality of blanched hazelnuts.
- Airtight Container: Store blanched and dried hazelnuts in an airtight container.
- Cool, Dark Place: Keep the container in a cool, dark, and dry place.
- Refrigerator or Freezer: For longer storage, store the hazelnuts in the refrigerator or freezer.
- Shelf Life: Properly stored blanched hazelnuts can last for several months.

Frequently Asked Questions About Blanching Hazelnuts
Why do I need to blanch hazelnuts at all?
Blanching removes the bitter brown skin, resulting in a sweeter, smoother tasting nut that is far more pleasant for consumption. Without blanching, the skin can impart an unpleasant, astringent flavor.
Can I blanch hazelnuts without roasting them first?
Yes, you can. However, roasting helps to loosen the skins, making the blanching and peeling process easier and more effective. Plus, roasting enhances the nut’s flavor.
How long should I blanch the hazelnuts?
Generally, blanching for 2-3 minutes in boiling water is sufficient. You’ll know they’re ready when the skins start to crack. Don’t over-blanch, or they’ll become mushy.
What if the skins are still difficult to remove after blanching?
If the skins are stubborn, you can try rubbing them in a colander or use a clean kitchen towel with more force. Sometimes a second brief blanch (30-60 seconds) is needed.
Is it necessary to use an ice bath after blanching?
Yes, the ice bath is crucial. It immediately stops the cooking process, preventing the hazelnuts from becoming overcooked and ensuring they maintain a firm texture.
Can I use blanched hazelnuts immediately after peeling them?
Yes, you can use them immediately, especially if you’re adding them to a recipe that requires further cooking. If storing, ensure they are completely dry.
How do I dry blanched hazelnuts?
The best way to dry blanched hazelnuts is to spread them on a baking sheet and bake them at a very low temperature (around 200°F or 95°C) for about 30 minutes, or until completely dry.
Can I blanch a large batch of hazelnuts at once?
You can, but it’s better to blanch in smaller batches to ensure even cooking. Overcrowding the pot can lower the water temperature and make the process less effective.
Do all hazelnut varieties blanch equally well?
No, some varieties are known to blanch more easily than others. Experiment to find your preferred type for blanching.
What if I burn the hazelnuts during roasting?
Unfortunately, burnt hazelnuts will have a bitter taste and may not be salvageable. It’s best to discard them and start with a fresh batch.
Can I blanch hazelnuts in the microwave?
While theoretically possible, microwaving is not recommended for blanching hazelnuts. It’s difficult to control the heat and ensure even cooking. The boiling water method provides much better results.
How do I know if my blanched hazelnuts have gone bad?
If the hazelnuts have a rancid smell or taste, or if they show signs of mold, they have gone bad and should be discarded. Proper storage is crucial to prevent spoilage.
