Distinguishing Black Walnuts from Other Varieties
Black walnuts have unique traits that set them apart from other walnut types. Their appearance, taste, and growing habits are different from common English walnuts.
Comparison with English Walnuts
Black walnuts have a darker, thicker shell than English walnuts. You’ll find it harder to crack open a black walnut. The nut meat inside is smaller and oilier.
Black walnuts have a strong, earthy flavor. English walnuts taste milder and sweeter. You might notice black walnuts have more tannins, giving them a bitter edge.
The trees themselves look different too. Black walnut trees grow taller and produce more juglone, a chemical that can harm other plants nearby.
When you buy walnuts at the store, you’re usually getting English walnuts. Black walnuts are less common and often gathered from wild trees.
Harvesting and Processing Black Walnuts
Black walnuts are a tasty treat, but they need careful handling and preparation. You’ll need to harvest, store, and crack them properly to enjoy their unique flavor.
Safe Handling and Storage
Wear gloves when picking black walnuts from the ground. The outer hulls can stain your hands.
Remove the green hulls right away. If they’re hard to remove, let the nuts sit for a few days until the hulls soften.
Rinse the nuts with water to clean off any dirt. Then, spread them out to dry in direct sunlight for a few days. This helps prevent mold.
Store your black walnuts in a cool, dry place. A garage or shed works well. Keep them in mesh bags or crates that allow air flow. They can last for several months this way.
Check your nuts often. Throw away any that show signs of mold or rot.
Cracking and Preparing Nutmeats
Black walnuts have very hard shells. You’ll need a special nutcracker or hammer to open them.
Place a nut on a hard surface and hit it with firm, quick taps until it cracks. Be careful of flying shell pieces. Wear safety glasses to protect your eyes.
Once cracked, use a nut pick to remove the nutmeat. It may come out in small pieces, but that’s normal for black walnuts.
Rinse the nutmeats in cool water to remove any shell bits. Then, spread them on a towel to dry.
You can eat black walnut pieces raw or use them in cooking. They’re great in baked goods, salads, and ice cream.
Store shelled black walnuts in an airtight container in the fridge. They’ll stay fresh for several months. You can also freeze them for up to a year.
Potential Side Effects and Drawbacks
Black walnuts can cause some unwanted effects when eaten. You might get an upset stomach or other digestive issues. This is more likely if you eat too many at once.
Some people are allergic to tree nuts, including black walnuts. If you have a nut allergy, avoid eating them. Signs of an allergic reaction can include:
- Itching or swelling in your mouth
- Hives on your skin
- Trouble breathing
Black walnut supplements may interact with certain medications. Talk to your doctor before taking them if you use any prescription drugs.
While black walnuts have some health benefits, they’re not a cure-all. Claims about their effects on skin conditions like psoriasis or eczema need more research.
The shells of black walnuts can stain your hands and clothes. Be careful when handling them, especially if they’re still in their green outer hulls.
Too much of any food can be bad for you. Eat black walnuts in moderation as part of a balanced diet. This helps you get their nutrients without overdoing it.
How and Where to Buy Black Walnuts
You can find black walnuts in several places. Many grocery stores carry them, especially during fall and winter. Look in the baking aisle or near other nuts.

If you live in an area where black walnut trees grow, you might find roadside stands selling them. This is most common in the Midwest and Eastern US.
