How to Make Walnut Extract: Step-By-Step

So here’s the core of how to make walnut extract, broken down into easy steps.
 
Once you get the hang of making walnut extract, you can adjust the ratios to suit your taste.
 

1. Gather Your Ingredients

To make walnut extract, you’ll need one cup of raw, unsalted walnuts and two cups of alcohol.
 
Vodka works great because it has a neutral flavor, but rum or brandy can add a nice twist.
 
You can also make walnut extract with food-grade glycerin if you want an alcohol-free version.
 
Just keep in mind glycerin takes longer and produces a slightly sweeter walnut extract.
 

2. Chop or Crush the Walnuts

The more surface area you expose, the faster your walnut extract will develop.
 
Give the walnuts a rough chop or a quick pulse in a food processor.
 
Don’t turn them into powder though, since fine bits are harder to strain later.
 
You just want broken pieces that release their oils and flavor into the walnut extract.
 

3. Combine and Seal

Place your chopped walnuts into a clean glass jar with a tight-fitting lid.
 
Pour the alcohol or glycerin over them until they’re fully submerged.
 
Shake the jar well, then store it in a cool, dark place like a pantry cabinet.
 
This is where the magic of making walnut extract really begins.
 

4. Let It Steep for Weeks

For the best walnut extract, let it steep for at least six to eight weeks.
 
Shake the jar every few days to help the flavors blend and speed up extraction.
 
You’ll notice the liquid darkening over time, which means your walnut extract is coming along nicely.
 
If you want a stronger walnut extract, you can let it sit even longer.
 

5. Strain and Bottle

Once the flavor is rich enough for you, strain the walnut extract through a fine mesh sieve lined with cheesecloth.
 
Give the walnuts a gentle squeeze to get every last drop of that flavorful walnut extract.
 
Pour the finished walnut extract into a dark glass bottle and label it with the date.
 
That’s really all there is to how to make walnut extract at home.
 

Tips for the Best Homemade Walnut Extract

A few small tweaks can take your walnut extract from good to absolutely amazing.
 

1. Toast the Walnuts First

Toasting the walnuts before you make walnut extract deepens the flavor and adds warmth.
 
Just spread them on a baking sheet and toast at 350°F for about eight to ten minutes.
 
Let them cool completely before adding them to your walnut extract.
 

2. Choose the Right Alcohol

For a clean, versatile walnut extract, vodka at 80 proof is your best bet.
 
If you want a warmer, richer walnut extract, try brandy or dark rum.
 
Whatever you choose, make sure it’s at least 70 proof for safe preservation.
 

3. Store It Properly

Homemade walnut extract lasts for years when kept in a cool, dark spot.
 
Keep it away from heat and direct sunlight to preserve that rich walnut flavor.
 
A small swing-top or dark glass bottle works perfectly for storing your walnut extract.
