How To Store Hazelnuts Long-Term

Choosing the Right Hazelnuts

When it comes to storing hazelnuts long-term, it all starts with choosing the right ones. Determining the quality of hazelnuts is crucial to ensure that you are storing the best possible nuts that will hold up well over time.

Look for hazelnuts that are plump, shiny, and free from any cracks or holes. You want to avoid any nuts that have a dull appearance or loose shells. By selecting high-quality hazelnuts from the start, you are setting yourself up for success in storing them for the long haul.

Determining the Quality of Hazelnuts

To determine the quality of hazelnuts, take a close look at their appearance. High-quality hazelnuts should be uniformly shaped and have a smooth surface. Avoid nuts that are discolored or have any visible mold. Give the nuts a gentle squeeze to ensure they feel firm and have a good weight to them.

Fresh hazelnuts will also emit a pleasant nutty aroma. By carefully examining the hazelnuts before purchasing or storing them, you can ensure that you are working with the best quality nuts.

Preferably Whole Hazelnuts

When it comes to long-term storage, it is preferable to choose whole hazelnuts instead of already shelled ones. Whole hazelnuts have a protective outer shell that helps preserve the nut’s freshness. Shelled hazelnuts are more susceptible to moisture and air exposure, which can lead to quicker spoilage.

By opting for whole hazelnuts, you are providing an extra layer of protection for the nuts, ensuring their longevity during storage.

Preparing Hazelnuts for Long-Term Storage

Before storing hazelnuts for the long term, it is important to prepare them properly. This preparation process involves removing the outer skin, blanching and roasting the nuts, and allowing them to cool.

Removing the Outer Skin

The outer skin of hazelnuts can have a slightly bitter taste, so it is recommended to remove it before storing the nuts long-term. To remove the skin, spread the hazelnuts in a single layer on a baking sheet and place them in an oven preheated to 350°F (175°C) for about 10-15 minutes.

After roasting, transfer the hazelnuts to a clean kitchen towel and rub them gently to remove the skin. The skin should come off easily, leaving behind the smooth and flavorful nut.

Blanching and Roasting Hazelnuts

Blanching hazelnuts is an optional step but can help enhance their flavor and texture. To blanch the hazelnuts, bring a pot of water to a boil and add the nuts. Let them boil for about 3-5 minutes, then remove them from the water and transfer them to a bowl of ice water to cool rapidly.

After blanching, spread the hazelnuts in a single layer on a baking sheet and roast them in the oven at 350°F (175°C) for about 10-15 minutes. Roasting the nuts adds a delicious aroma and deepens their flavor.

Allowing the Hazelnuts to Cool

After blanching and/or roasting the hazelnuts, it is important to allow them to cool completely before storing them. The cooling process allows the nuts to reach room temperature and ensures that they are not warm or moist when placed in storage.

Place the hazelnuts on a clean kitchen towel or a wire rack and let them sit undisturbed until they are cool to the touch. Once cooled, the hazelnuts are ready for long-term storage.

Selecting the Ideal Storage Container

Selecting the right storage container for your hazelnuts is essential to maintain their freshness and prolong their shelf life. Opting for airtight containers, such as jars or plastic bags, is recommended to prevent air and moisture from reaching the nuts.

Before freezing hazelnuts, it is important to package them properly to protect against freezer burn and minimize air exposure. Divide the nuts into small batches that you will use in one go to minimize the need for repeated freezing and thawing.

Place the nuts in freezer-safe bags or airtight containers, removing as much air as possible before sealing. For added protection, you can also wrap the containers in aluminum foil or place them inside a freezer bag for an extra layer of insulation.

Using Freezer-Safe Containers

Freezer-safe containers are designed to withstand low temperatures without cracking or breaking. When freezing hazelnuts, opt for containers made from materials specifically labeled as freezer-safe.

Glass containers with tight-sealing lids or heavy-duty plastic bags with zip locks are excellent choices for freezing hazelnuts. Make sure the containers are properly sealed to prevent air and moisture from reaching the nuts.

Labeling and Dating Packages

To avoid confusion and ensure you use the oldest nuts first, it is important to label and date the packages of frozen hazelnuts. Use a marker or labels to clearly indicate the contents and freezing date on each container.

This simple step helps you keep track of the freshness of your hazelnuts and enables you to use them in a timely manner. Proper labeling eliminates guesswork and ensures optimal flavor when utilizing the frozen hazelnuts in recipes.

Using Vacuum Sealing for Long-Term Storage

Vacuum sealing is another effective method for long-term storage of hazelnuts. By removing the air from the package, vacuum sealing creates an oxygen-free environment that helps prevent spoilage and maintain the nuts’ freshness.

Vacuum Sealing Hazelnuts

To vacuum seal hazelnuts, you will need a quality vacuum sealer. Place the hazelnuts in a vacuum sealing bag or roll and seal one end according to the manufacturer’s instructions.

Insert the open end of the bag into the vacuum sealer, close the lid, and start the vacuum sealing process. The machine will remove the air from the bag and create a tight seal, keeping the hazelnuts fresh for an extended period.

Selecting a Quality Vacuum Sealer

Investing in a quality vacuum sealer is essential for effective long-term storage of hazelnuts. Look for a vacuum sealer that offers a strong sealing capability and a reliable suction power to ensure proper air removal.

Read reviews and compare features before making a purchase. A sturdy and dependable vacuum sealer will not only help preserve the freshness of your hazelnuts but also be useful for storing other perishable items in the future.

Monitoring for Any Re-Sealing Issues

While vacuum sealing provides excellent long-term storage for hazelnuts, it is important to periodically check for any re-sealing issues. Over time, the seal on the vacuum-sealed bag or roll may weaken, allowing air to reintroduce itself.

Regularly inspect the bags or rolls for any signs of air leakage or compromised seals. If you notice any issues, reseal the package or transfer the hazelnuts to a new vacuum-sealed bag to maintain optimal freshness.

Checking for Hazelnut Rancidity Regularly

To ensure that your stored hazelnuts remain fresh and free from rancidity, it is important to check them regularly. Recognizing signs of rancidity, performing a sniff test, and occasionally tasting the hazelnuts are all steps you can take to determine their freshness.
