If possible, purchase hazelnuts that are still in their shells as this helps protect them from moisture and air, preserving their natural oils and freshness.

2. Shell the Nuts:
Before preserving hazelnuts, you need to shell them. This can be done by using a nutcracker or by gently tapping the nuts with a hammer. Once shelled, remove any loose shell fragments and discard any nuts that appear discolored or moldy.

3. Blanch and Toast:
To enhance the flavor and texture of hazelnuts before preservation, you can blanch and them. Bring a pot of water to a boil and blanch the nuts for approximately one minute. Drain and immediately transfer the nuts to a baking sheet. Toast in a preheated oven at 350°F (175°C) for about 10-15 minutes, or until they become golden brown. Toasting hazelnuts helps to bring out their natural oils, intensifying their taste.

4. Cool and Package:
Once toasted, remove the hazelnuts from the oven and allow them to cool completely. This helps prevent condensation buildup, which can lead to the nuts becoming stale or moldy during storage. Once cooled, package the nuts in airtight containers such as glass jars or resealable plastic bags. Make sure the containers are clean and dry before use and fill them up to avoid excess air contact.

5. Refrigerate or Freeze:
To maximize the shelf life of hazelnuts, it is best to refrigerate or freeze them. Place the airtight containers in the refrigerator if you plan to use the nuts within a few months. Stored this way, hazelnuts can retain their flavor and quality for up to six months. If you want to preserve them for an even longer period, store the containers in the freezer. Frozen hazelnuts can remain fresh for up to one year when properly sealed.

6. Utilize Proper Thawing Techniques:
When you are ready to use the preserved hazelnuts, it is essential to thaw them properly. Remove the desired amount of nuts from the freezer and place them in the refrigerator overnight. Slow thawing in the refrigerator helps prevent condensation and moisture buildup, which can lead to a loss of texture and flavor. Avoid thawing hazelnuts at room temperature or using a microwave, as quick thawing methods can affect the nut’s quality.
