Going Nutty, Week Ending 10/14/18

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.

Yep, black walnut stains!

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.

Almost ... there ...

Almost … there …

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!

Foraging Finds, Week Ending 8/19/2018

You guys, I found BUTTERNUT! … Maybe!

No, not a feral squash … or even an invasive domesticated squash overtaking the rest of my garden. (I already knew where that was!)

Nope, what I found was evidence of a butternut tree (Juglans cinerea) when I picked up a funny shaped nut. I’d assumed I had a better chance of finding morels than butternut trees, thanks to a fungal disease (cleverly called ‘butternut canker’) which had largely decimated the wild population. The Maryland Biodiversity Project even categorizes butternut trees as “state rare”.

But I found one, less than a mile from my house. And then a week later, I located another possible butternut near a friend’s house in Washington county. One of the key characteristics is the shape of the nut. The hull has a oblong, almost football shape. The nut inside has a prominent beak on one side.

Butternuts are cousins to the more prevalent black walnut (Juglans nigra). I haven’t foraged black walnuts because they feature thick, black-staining hulls and difficult-to-crack shells. Accumulating enough nutmeat for a recipe or snacking takes significant time and effort. Additionally, the flavor of black walnut does not appeal to everyone. You can sometimes find black walnuts in grocery stores, if you want to taste them to decide if they are worth the effort. (Or Amazon.com. Everything is on Amazon.)

(Immature black walnuts can also be used to make a liqueur called nocino, but I’ve already missed the window for this particular experiment.)

Butternuts, by contrast, are described as having delicious nutmeats…buttery flavored, even. I haven’t tried it yet because the butternut-shaped-nut had a cracked hull, so the nut inside was probably compromised.

I couldn’t tell the potential butternut tree from surrounding black walnut trees. Also I have struggled to tell black walnuts (or butternuts) from staghorn sumac or tree of heaven (especially at a distance). They all have  compound leaves with pointy, lance-shaped leaflets. Staghorn sumac tends to be shorter (35 ft), and up close the leaves have serrated margins. For females, the red drupes are a dead giveaway. Tree of heaven is more problematic, because the trees can grow as tall as black walnut (80 ft). But if you get close (i.e., not gazing at trees flying by as you hurtle down the interstate), the bark is a smooth light gray versus the deep furrows of walnut bark.

In the summer though, you know for sure if you have a black walnut if you spot the round green shapes of future nuts in the trees.

To complicate butternut identification, there are also hybrid butternuts, which the nuts shown below may have been. Note their less pointy shape than the nut in the first picture.  It can be hard to tell the hybrids from the full butternuts, but hopefully either will be just as tasty.

Apparently some years butternuts produce a good crop, and some years there is no crop at all. I’ll definitely be back to check on both trees later this year to harvest the actual nuts.

Everyone recommends wearing gloves or plastic bags over your hands when removing the hulls to prevent staining, unless “diseased” is the look you are trying for. I have read suggestions for stomping the nuts, or driving over them with cars.  You can also use a wooden board with a hole in it, and a mallet or second board to force the nut through hole, scraping off the hull. Other sources recommend just using a sharp knife to peel away the husks. (Carefully, of course!)

The nuts are also very difficult to crack.  Regular nutcrackers aren’t up to the task. One book recommended pouring boiling water over the nuts, letting them stand for 15 minutes and then trying to crack the shells with a hammer tap. Butternuts can be eaten right away, unlike black walnuts which should be allowed to fully dry and ripen in their shells for several weeks or months.

Will all the work – identifying, harvesting, hulling, shelling, and finally using the nuts – be worth it? Stay tuned! We’ll find out!
