Growing your own hazelnuts offers the satisfaction of harvesting fresh, flavorful nuts right from your backyard. However, getting those nuts from tree to table requires understanding the entire process, from recognizing when they’re ripe to properly curing and preparing them for consumption. This guide provides a comprehensive look at how to prepare hazelnuts from a tree, ensuring you enjoy the best possible flavor and texture.
Recognizing Hazelnut Ripeness and Harvesting
Knowing when to harvest hazelnuts is crucial. Picking them too early results in bland, shriveled nuts, while waiting too long risks losing them to squirrels and other wildlife or letting them rot on the ground.
Signs of Maturity
The key indicators of hazelnut ripeness are visual cues. Look for these signs:
- Browning Husks: The leafy husk surrounding the nut will turn from green to brown or yellowish-brown. This is perhaps the most reliable indicator.
- Nut Drop: Mature hazelnuts naturally fall from the tree. Regularly check the ground beneath your hazelnut tree for fallen nuts.
- Easy Husk Removal: The husk should easily separate from the nut. If you have to force it, the nut is likely not fully ripe.
- Nut Color: The shell of the hazelnut should be a rich, even brown color. Avoid harvesting nuts with pale or green shells.
Harvesting Techniques
While some nuts will fall naturally, you may want to assist the process, especially if you anticipate animal predation.
- Ground Collection: The simplest method is to collect fallen nuts from the ground. Rake around the tree to gather them efficiently. Remove any debris, leaves, or decayed nuts.
- Gentle Shaking: Gently shake the branches of the tree. Ripe nuts will detach and fall to the ground. Avoid excessive force, which can damage the tree.
- Hand Picking: For nuts that are nearly ripe but haven’t fallen, you can gently pick them by hand. Choose nuts with browned husks that easily detach.
Post-Harvest Handling
Once harvested, prompt attention is vital to prevent mold and ensure proper curing.
- Remove Husks: Remove the husks from the nuts as soon as possible after harvest. This prevents moisture from being trapped against the shell, which can lead to mold growth.
- Initial Cleaning: Rinse the nuts with clean water to remove any dirt or debris. Spread them out on a clean surface to air dry briefly before proceeding to the curing process.
Curing Hazelnuts for Optimal Flavor
Curing is an essential step in preparing hazelnuts. It allows the nuts to dry slowly, developing their characteristic flavor and preventing spoilage.
The Importance of Curing
Curing significantly impacts the quality of your hazelnuts:
- Flavor Development: Slow drying enhances the nutty flavor of the hazelnuts.
- Moisture Reduction: Curing reduces the moisture content, preventing mold and extending shelf life.
- Improved Texture: Properly cured hazelnuts have a crisp, satisfying texture.
Curing Methods
Several methods can be used to cure hazelnuts. Choose the one that best suits your climate and resources.
- Air Drying: This is the most common and simplest method. Spread the hazelnuts in a single layer on screens, trays, or burlap sacks in a well-ventilated, dry location. A garage, shed, or attic works well. Ensure air circulates freely around the nuts. Turn them regularly (every day or two) to ensure even drying.
- Dehydrator Drying: A food dehydrator can expedite the drying process. Spread the nuts in a single layer on the dehydrator trays and set the temperature to around 100-110°F (38-43°C). Check the nuts periodically and remove them when they are thoroughly dry.
- Oven Drying (Low Heat): In a pinch, you can use your oven. Spread the nuts in a single layer on a baking sheet and set the oven to the lowest possible temperature (ideally below 200°F or 93°C). Leave the oven door slightly ajar to allow moisture to escape. Monitor the nuts closely to prevent burning.
Determining Curing Completion
Knowing when the curing process is complete is essential. Here’s how to tell:
- Nut Kernel Shrinkage: The kernel inside the shell will shrink slightly and separate from the shell.
- Crisp Texture: The nuts should be crisp and brittle when you bite into them.
- Shell Sound: When you shake the nut, you should hear the kernel rattling inside.
The curing process typically takes 2-6 weeks, depending on the humidity and temperature.
Storing Hazelnuts to Preserve Freshness
Proper storage is vital to maintain the quality of your cured hazelnuts. The goal is to prevent moisture absorption and protect them from pests.
Optimal Storage Conditions
These conditions are ideal for storing hazelnuts:
- Cool Temperature: Store hazelnuts in a cool environment, ideally between 32-40°F (0-4°C).
- Dry Environment: Avoid humid environments, as moisture can lead to mold growth.
- Airtight Containers: Use airtight containers, such as glass jars or resealable plastic bags, to protect the nuts from moisture and pests.
Storage Methods
Consider these storage options:
- Refrigeration: Refrigerating hazelnuts can extend their shelf life for several months.
- Freezing: Freezing is an excellent option for long-term storage. Hazelnuts can be frozen for up to a year without significant loss of quality.
Preparing Hazelnuts for Consumption
Once your hazelnuts are cured and stored, you can prepare them for eating. This typically involves roasting and removing the skins.
Roasting Hazelnuts: Enhancing Flavor
Roasting hazelnuts enhances their flavor and makes them more palatable.
- Spread on Baking Sheet: Preheat your oven to 350°F (175°C). Spread the hazelnuts in a single layer on a baking sheet.
- Roast: Roast the nuts for 10-15 minutes, or until they are fragrant and the skins begin to crack. Keep a close watch to prevent burning.
- Cool: Remove the nuts from the oven and let them cool slightly.
Removing Hazelnut Skins: A Necessary Step
Removing the skins improves the texture and flavor of roasted hazelnuts.
- Towel Method: Place the slightly cooled nuts in a clean kitchen towel. Fold the towel over the nuts and rub them vigorously. The skins should loosen and flake off.
- Colander Method: After rubbing in a towel, transfer the nuts to a colander and shake vigorously. This helps remove the loosened skins.
Not all skins will come off completely, and that’s okay. The goal is to remove the majority of them.
Culinary Uses for Prepared Hazelnuts
Roasted and skinned hazelnuts are incredibly versatile.
- Snacking: Enjoy them as a healthy and delicious snack.
- Baking: Add them to cookies, cakes, and breads.
- Salads: Sprinkle them on salads for added flavor and texture.

When is the best time to harvest hazelnuts?
The ideal time to harvest hazelnuts is typically in the late summer or early fall, usually between late August and October, depending on your local climate and the specific variety of hazelnut tree you have. Look for signs that the nuts are mature, such as the husks turning brown and starting to split open, and the nuts themselves beginning to drop from the tree naturally. A gentle shake of the branches will often dislodge the ripe nuts that are ready for harvesting.
Avoid harvesting too early, as the nuts may not be fully developed and will lack the rich flavor and texture you’re looking for. However, delaying the harvest for too long can lead to the nuts being taken by squirrels and other wildlife, or becoming damaged by the elements. Regularly checking your trees during the harvest window will help you determine the optimal time to gather your hazelnuts.
How do I properly cure hazelnuts after harvesting?
Curing hazelnuts is crucial for improving their flavor, reducing moisture content, and extending their shelf life. The process involves spreading the freshly harvested nuts in a single layer on screens or trays in a well-ventilated, dry area away from direct sunlight. A garage, shed, or covered porch works well. Make sure there’s adequate airflow to prevent mold growth.
Allow the hazelnuts to cure for two to four weeks, or until the kernels inside the shells are crisp and easily separated from the inner skin. Turn the nuts occasionally to ensure even drying. You’ll know they’re properly cured when they rattle inside their shells and the moisture content is sufficiently reduced, typically below 10%.
What’s the best way to store cured hazelnuts?
Once your hazelnuts are properly cured, proper storage is essential to maintain their quality. The most important factor is keeping them dry and away from pests. Store the nuts in airtight containers, such as jars, plastic bags, or metal containers. These containers should be placed in a cool, dark, and dry location, such as a pantry or refrigerator.
Hazelnuts can also be frozen to extend their shelf life even further. Place the nuts in freezer-safe bags or containers, removing as much air as possible. Frozen hazelnuts can last for up to a year or even longer. When you’re ready to use them, simply thaw them at room temperature or use them directly from frozen in recipes.
How do I remove the skins from hazelnuts?
Removing the skins from hazelnuts can improve their flavor and texture, especially when using them in baking or cooking. There are several methods, but the most common involves roasting the nuts in a preheated oven at 350°F (175°C) for about 10-15 minutes, or until the skins start to crack and blister. Watch them closely to prevent burning.
Once roasted, transfer the hot hazelnuts to a clean kitchen towel and rub them vigorously. The friction should loosen and remove a significant portion of the skins. Some skins may be stubborn and require individual attention. If necessary, you can use a small knife or your fingers to peel off any remaining skins. Don’t worry about removing every last bit of skin, as a few remnants won’t significantly affect the flavor.
Can I eat hazelnuts straight from the tree?
While technically you can eat hazelnuts straight from the tree, it’s generally not recommended. Freshly harvested hazelnuts typically have a higher moisture content and a less developed flavor compared to cured nuts. The kernels may also be softer and less crunchy.
The curing process is essential for reducing moisture, concentrating the flavor, and achieving the desired crisp texture that makes hazelnuts so enjoyable. Eating uncured hazelnuts won’t be harmful, but you’ll likely find the taste and texture to be less appealing. It’s always best to cure your hazelnuts before consuming them for the optimal flavor and experience.
How do I know if my hazelnuts have gone bad?
Hazelnuts, like other nuts, can go bad if not stored properly or if they’ve been stored for too long. The most common signs of spoilage are a rancid or bitter taste and smell. This is due to the oils in the nuts oxidizing, which can happen over time, especially when exposed to heat, light, or air.
Other signs of spoilage include a shriveled or discolored appearance, or the presence of mold. If you notice any of these signs, it’s best to discard the hazelnuts to avoid consuming something that could be unpleasant or even harmful. Properly storing your hazelnuts in airtight containers in a cool, dark, and dry place will help to prevent them from going bad quickly.
Are there any specific tools or equipment that are helpful for harvesting and processing hazelnuts?
While you can harvest and process hazelnuts with minimal equipment, a few tools can make the process easier and more efficient. For harvesting, a sturdy rake or nut gathering tool can help you collect fallen nuts from the ground. A large tarp or sheet placed under the tree can also simplify cleanup.
For processing, screens or trays for curing, airtight containers for storage, and a clean kitchen towel for removing skins after roasting are all helpful. A nutcracker can be useful for cracking the shells, although you can also use a hammer or other suitable tool. While not essential, these tools can streamline the process and help you get the most out of your hazelnut harvest.
