How To Make Black Walnut Oil?

For those who don't know, walnut oil is made by cracking open walnuts, grinding the kernels into a fine powder, and then pressing the oil out.

This is a simple process but requires the right technique and tools to produce an ingredient that is not only great for cooking but also offers many health benefits, especially in skincare, haircare, and digestive support.

In this article, we will explore in detail how to make walnut oil at home and the health benefits that this oil brings.

What Is Black Walnut Oil?

Black walnut oil is a natural oil extracted from the kernels of the black walnut tree (Juglans nigra), a native species of tree in the United States. This oil is known for its rich, earthy flavor that provides a unique taste experience, suitable for many traditional cooking methods.

The kernel of the black walnut contains tannins, a compound that may help reduce irritation. The mild astringent properties of tannins have led to the use of black walnut oil for topical skin issues in mild cases.

However, despite its widespread use in traditional remedies, there is insufficient scientific evidence to support the specific health benefits of black walnut oil.

How To Make Black Walnut Oil

Method 1: 100% Black Walnut Oil

This method uses an oil press to extract pure black walnut oil, resulting in a rich flavor while retaining maximum nutrients. This method requires a home oil press and can yield about 1.5 liters of finished oil.

Ingredients and Tools:

• 2.7 kg of whole black walnuts (or 1.35 kg of shelled walnuts)
• Nutcracker (for whole walnuts)
• Food processor
• Oil press
• Baking tray
• Filter cloth or filter bag.

Instructions:

1. Prepare the walnuts: If using whole walnuts, crack the shells to extract the kernels. Skip this step if you already have shelled walnuts.
2. Grind the walnuts: Place the walnut kernels into the food processor and grind them into a fine walnut powder, being careful not to grind for too long to avoid releasing oil prematurely.
3. Roast to increase oil yield: Spread the walnut powder on a baking tray and roast at 375°F (190°C) for about 5 minutes to enhance flavor and increase oil yield.
4. Press the oil: Place the roasted walnut powder into the oil press and extract the oil. For a clearer oil, you can filter it through a cloth or filter bag to remove any remaining solids.
5. Storage: Pour the oil into dark-colored bottles and store it in the refrigerator, where it can last up to 2 months.

Method 2: Black Walnut Infused Oil

If you don't have an oil press, you can still make infused black walnut oil to enjoy its distinctive flavor. This method uses vegetable oil or olive oil as a solvent to carry the walnut flavor.

Ingredients and Tools:

• ¾ cup of black walnut kernels
• ¼ cup of vegetable oil or olive oil
• Food processor
• Jar or glass bottle

Instructions:

1. Boil and roast the walnuts: Boil the walnut kernels for 3 minutes to soften them, then drain. Spread the walnut kernels on a baking tray and roast at 350°F (175°C) for about 15 minutes, stirring halfway through.
2. Grind the walnuts: Let the walnuts cool, then grind them into small pieces (do not grind too finely).
3. Infuse the oil: Place the ground walnuts into a jar or bottle, pour the oil over them, and let it steep for several days to allow the oil to absorb the walnut flavor.
4. Usage: After a few days, the walnut-infused oil can be used for salads and other traditional dishes.

Method 3: Making Oil From Black Walnuts Powder

In this method, you will use black walnut powder made from dried and finely ground walnut shells. The oil extracted from the powder will have a stronger walnut flavor.

Ingredients and Tools:

• Black walnut shells (or black walnut powder)
• Food dehydrator or oven
• Grinder
• Vegetable oil or olive oil
• Jar or glass bottle

Instructions:

1. Dehydrate the walnut shells: If using fresh walnut shells, dehydrate them completely in a food dehydrator for 2 days or in a low-temperature oven until fully dry.
2. Grind into powder: Once the shells are dry, use a grinder to crush them into a fine powder.
3. Infuse the oil: Place the walnut powder into a jar along with vegetable oil or olive oil, and let it steep for 24 hours. You may gently warm the mixture to enhance the infusion process but avoid overheating.
4. Filter and store: Filter the oil through a cloth or filter bag, then store it in a dark bottle.

How To Store And Use Black Walnut Oil

Black walnut oil is a valuable ingredient for health, but to maintain its quality and effectiveness, you need to store and use it properly. Here are some guidelines to help you optimize the storage and usage of black walnut oil:

How to store black walnut oil:

• Buy or make a small quantity and use it frequently: Since black walnut oil is prone to oxidation, it’s best to buy it in small amounts and replenish it as needed to avoid storing it for too long.
• Store in a dry, cool place: Like other oils, black walnut oil should be stored in a dry place, away from direct sunlight and high heat sources.
• Use within six months after opening: Unopened black walnut oil can be stored for up to 24 months. However, after opening, it should be used within six months to ensure the best flavor and quality.

How to use black walnut oil:

• Drizzle on dishes: Add a few drops of black walnut oil to steamed fish, roasted vegetables, pasta, or cheese to enhance the flavor.
• Mix with salads: Replace vinaigrette with black walnut oil to enhance the rich taste, perfect for green salads or mixed seed dishes.
• Add to desserts: You can add a few drops of black walnut oil to brownies, sweet breads, or apple crisps to increase the richness and aroma.
• Sauté vegetables at low heat: If you prefer stir-fried dishes, use black walnut oil instead of regular cooking oils.

Black Walnut Oil Vs Black Walnut Capsule: Which Is Better?

Choosing between black walnut oil and black walnut capsules depends on your needs and lifestyle. If you need a versatile product that can be applied topically or used as a cooking ingredient, black walnut oil is the right choice.

On the other hand, if you need an easy, no-fuss supplement that is convenient for on-the-go use, black walnut capsules will serve your needs better.

Additionally, capsules are pre-dosed, making it easier to control your daily intake. For those who want to maximize the health benefits of black walnuts for digestive and immune support without worrying about storage or preparation, capsules may be the better option.

Other Ways To Use Black Walnuts for Health

Besides being used to make oil, black walnuts can be consumed in various forms, such as:

• Black Walnut Tincture: Known for its astringent properties, tincture made from black walnut shells can help soothe digestive issues and balance yeast levels in the body.
• Black Walnut Tea: The leaves and shells of black walnuts can be used to brew tea, a gentler way to take advantage of the benefits of this nut.
• Black Walnut Powder: The powdered form can be added to dishes or beverages. It’s an easy way to incorporate nutrients without needing to cook or prepare complex recipes.
• Black Walnut Supplements: These products are manufactured under expert supervision, ensuring they provide the right amount of nutrients while minimizing health risks.
