Fall is definitely nut season in central Maryland and much of the southeast. We’re lucky to have so many edible nuts locally. They require more work than just buying nuts at the store, but they are free and abundant. It’s a shame not harvest them!
Disclaimer: This is my first year seriously foraging and trying to incorporate wild foods into my diet. So everything you read here is based on research, not my own personal experience. Yet. I might move this post to its own page eventually as I actually practice the techniques described.
I’ve already discussed black walnut (Juglans nigra) on several occasions. If you live in this area, you cannot miss them. Their branches overhang local roads, where passing cars smear the pavement brown as they crush the walnut hulls. This is a dangerous time of year to stand under black walnut trees!
Most sources say to remove the thick green husk immediately to prevent it from changing the flavor of the nut inside as the husk degrades. The husks can also get moldy. Various removal techniques include the following:
- Using a hammer to loosen them, then prying them off
- Boot stomping them
- Using a knife
- Running over them with a car in the driveway
- Smashing them between two rocks
I used the last technique, which may be less effective, but is primally quite satisfying.
Just remember anything that touches the hulls will get stained dark brown or black, so factor that into your chosen hull-removal method. Also if you wear gloves, they, um, need to be water / hull juice proof… don’t ask me how I know.
After removing the hulls, by whatever method, wash off any remaining bits clinging to the nut. (Stay out of the spray zone though!) Once the job of husk removal is done, let the nuts air dry for several weeks before eating. Some sources say as long as two months. The challenge is finding a way to let them dry while protecting them from squirrels. Luckily my yard lacks these critters, but there is no point in taking risks! My plan is to hang the nuts in mesh bags (the kind grocery store bulk onions are sold in). For now, they are hanging outside our shed when the weather is clear, and I move them inside when rain threatens. Your mileage may vary – if outside is problematic (due to weather or squirrels), a cool room in the house might work.
If you plan to store black walnuts for the long term, leave them in their shell. The nutmeats go rancid more quickly without their shell, and will need to be stored in the refrigerator or freezer.
Cracking the nuts is a challenge as well. The wall is very thick, and the internals convoluted, resulting in broken bits of nutmeat rather than the perfect halves from store bought walnuts. They also make special nutcrackers specifically for tough shells like black walnut. I plan to use a bench vise grip to gently crush the shells, hopefully in a way that doesn’t completely compromise the meat.
Now is also the perfect time to locate black walnut tree with nuts within your reach. Why? In the July time frame, unripe black walnuts can be used to make a local variety of nocino, a type of liqueur that originated in Italy. While ripe walnuts are easily harvested from the ground, unripe walnuts must be plucked from the tree, which is challenging when most black walnuts tower above your head. If you start a batch of nocino around July 4, it will be ready in time for Christmas festivities. But you need to know now which trees will have unripe fruit that you can actually reach then.
In upcoming posts, I hope to include some recipes for black walnuts, so if you’re following along at home you’ll know how to use them!
