How To Prepare Black Walnuts

Preparing black walnuts is a rewarding process that turns a backyard nuisance into a delicious, gourmet treat.
 
If you’ve ever wondered how to prepare black walnuts, the answer starts with harvesting them at the right time and then curing, hulling, drying, and cracking them properly.
 
Black walnuts have a bold, earthy flavor that’s much stronger than the store-bought English walnuts most people are used to.
 
But their tough hulls and rock-hard shells mean you can’t just crack them open and eat them right away.
 
In this post, we’ll walk through how to prepare black walnuts step by step so you can enjoy your harvest all year long.
 
Let’s dive in.
 

How to Prepare Black Walnuts: The Full Process

Learning how to prepare black walnuts takes a little patience, but the payoff is worth it.
 
Here’s the step-by-step process for preparing black walnuts from tree to table.
 

1. Harvest at the Right Time

The first step in how to prepare black walnuts is knowing when to pick them.
 
Black walnuts ripen in late summer through early fall, usually between September and October depending on your region.
 
You’ll know they’re ready when the green outer hulls start turning yellow and the nuts begin dropping to the ground.
 
Don’t pick them straight off the tree if you can help it.
 
The best nuts are the ones that have fallen on their own, since that means they’re fully mature.
 

2. Remove the Hulls Promptly

Once you’ve gathered your black walnuts, you need to remove the hulls as soon as possible to avoid rot and mold.
 
Here’s the thing, though: black walnut hulls stain everything they touch.
 
They’ll turn your hands yellow-brown for weeks, so always wear heavy-duty rubber gloves.
 
The easiest way to hull them is to spread the nuts on a hard surface like a driveway and step on them or roll them under your boot.
 
You can also use a hammer or a specialized hulling tool for larger batches.
 
Aim to remove the hulls within a day or two of harvesting for the best results.
 

3. Wash and Rinse the Nuts

After hulling, you’ll want to rinse the nuts thoroughly with a garden hose or in a bucket of water.
 
This step in how to prepare black walnuts removes leftover hull bits and any debris.
 
A quick tip is to dump the nuts in a bucket of water and toss out any that float.
 
Floaters usually mean the nut inside is shriveled or empty, so they’re not worth keeping.
 
The ones that sink are the good ones.
 

4. Cure the Nuts for Several Weeks

Curing is the part of how to prepare black walnuts that most people skip, and that’s a mistake.
 
Fresh black walnuts are too moist and their flavor hasn’t fully developed yet.
 
Spread the cleaned nuts in a single layer in a cool, dry, well-ventilated area, like a garage, shed, or screen door.
 
Let them cure for at least two to four weeks, stirring them occasionally so they dry evenly.
 
You’ll know they’re cured when the shells feel hard and dry and the nuts rattle slightly when shaken.
 

How to Crack and Store Black Walnuts

Now that your nuts are cured, it’s time to crack them open and store the good stuff.
 
Here’s how to crack and store black walnuts the right way.
 

1. Use the Right Cracking Technique

Black walnut shells are incredibly hard, so you need a sturdy nutcracker or a hammer and a hard surface.
 
The trick to how to prepare black walnuts at this stage is to strike the pointed end of the shell, not the flat side.
 
A firm tap with a hammer usually does the job without crushing the nutmeat inside.
 
Work on a hard, stable surface and wear safety glasses, since shell fragments can fly.
 

2. Pick Out the Nutmeats

Once cracked, use a nut pick or a small knife to pull out the nutmeats.
 
Black walnut kernels are smaller and more delicate than English walnuts, so take your time.
 
Don’t worry if you end up with some broken pieces, they taste just as good in baking and cooking.
 

3. Store Them Properly

Storing your black walnuts correctly keeps them fresh for months.
 
Place shelled nutmeats in an airtight container or freezer bag.
 
You can keep them in the fridge for up to six months or in the freezer for up to two years.
 
If you leave them in the shell, they’ll last even longer, sometimes up to a year in a cool, dry spot.
 

So, How Do You Prepare Black Walnuts?

Preparing black walnuts means harvesting them when the hulls start to yellow, removing the hulls promptly, rinsing, curing for weeks, and then cracking and storing the nutmeats.
 
It’s a bit of work, but the rich, bold flavor of fresh black walnuts is something you simply can’t buy at the grocery store.
 
Just remember to wear gloves, cure them properly, and store them well, and you’ll have a stash of delicious nuts to enjoy all winter.
 
Now you know exactly how to prepare black walnuts from start to finish, so go grab your harvest and get cracking.
