How to Make Black Walnut Flavoring: 3 Simple Methods
There are several ways to make black walnut flavoring, and each one gives you a slightly different result.
Let’s go through the most popular methods so you can pick the one that fits your kitchen and your timeline.
1. Alcohol Extraction Method
This is the most common way to make black walnut flavoring.
Start by cracking about 12 to 15 black walnuts and collecting the nutmeats.
Chop them roughly and place them in a clean glass jar.
Pour in enough vodka, rum, or bourbon to cover the nuts completely.
Seal the jar and store it in a cool, dark place for four to six weeks.
Shake the jar every few days to help the flavors develop.
After a month, strain the liquid through a fine mesh sieve or cheesecloth.
What you’re left with is a potent black walnut flavoring that’s ready to use.
2. Simmering Method
If you want to make black walnut flavoring without alcohol, the simmering method works beautifully.
Combine chopped black walnuts with water in a saucepan.
Use about one cup of nuts for every two cups of water.
Bring it to a gentle simmer and let it cook for about 30 to 40 minutes.
The liquid will reduce and take on a deep black walnut color.
Strain the mixture and let it cool.
This version of black walnut flavoring is less shelf-stable, so store it in the fridge and use it within a couple of weeks.
3. Black Walnut Syrup Method
For a sweeter take, you can make black walnut flavoring as a syrup.
Combine one cup of sugar, one cup of water, and half a cup of chopped black walnuts.
Simmer until the sugar dissolves and the mixture thickens slightly.
Strain out the nuts and pour the syrup into a bottle.
This black walnut flavoring is perfect for drizzling over pancakes, ice cream, or oatmeal.
It’s not as concentrated as the alcohol version, but it’s delicious in its own right.
Tips for Making the Best Black Walnut Flavoring
Making black walnut flavoring is pretty forgiving, but a few tips can make a big difference.
First, always use fresh black walnuts.
Old or rancid nuts will ruin your black walnut flavoring.
Second, toast the nuts lightly before you start.
This deepens the flavor and makes your black walnut flavoring taste even richer.
Third, be patient.
The longer you let the black walnuts steep, the more intense your black walnut flavoring will be.
Finally, store your finished black walnut flavoring in a dark glass bottle away from heat and light.
That way it stays fresh for months.
So, How Do You Make Black Walnut Flavoring?
You make black walnut flavoring by extracting the flavor from black walnuts using alcohol, water, or a sugar syrup.
The alcohol method gives you the strongest and longest-lasting black walnut flavoring.
The simmering method is great if you want to avoid alcohol.
And the syrup method is perfect for sweet applications.
No matter which method you choose, making black walnut flavoring at home is rewarding and surprisingly easy.
Grab some black walnuts, pick your method, and make your own black walnut flavoring.
Once you do, you’ll never go back to store-bought black walnut flavoring again.
