Black walnuts, with their rich, distinct flavor, are a hidden gem in the world of nuts. Whether you have a yard filled with these majestic trees or plan to forage in a local forest, learning when and how to harvest them can be a rewarding experience. In this article, we'll explore the ins and outs of black walnut harvesting and share essential tips for cracking their notoriously tough shells.
When to Harvest Black Walnuts
The ideal time to harvest black walnuts is in the fall, typically from late September to early October. You can tell that the walnuts are ready for harvest when the outer husks start to turn from green to yellow - brown and begin to split open. At this stage, the nuts inside are fully mature. To check if the walnuts are ripe, gently squeeze the husk. If it gives way easily and starts to split, it's a good sign that the nut is ready for collection.
How to Harvest Black Walnuts
Harvesting black walnuts can be a bit labor - intensive, but it's well worth the effort. First, gather the necessary tools: a long - handled pole with a hook or a nut picker, a bucket or a large container, and gloves. The gloves are essential because the husks of black walnuts contain a natural dye that can stain your hands and clothing.
Start by using the pole to knock down the walnuts from the tree branches. If the walnuts have already fallen to the ground, use the nut picker to collect them. As you collect the walnuts, place them in the container. Make sure to sort through the collected nuts and discard any that are damaged or moldy.
Processing the Harvested Black Walnuts
Once you've harvested the black walnuts, the next step is to remove the outer husks. You can do this by placing the walnuts in a large bin and running over them with a lawn mower or by using a nut - husking machine. If you're doing it by hand, wear gloves and use a hammer or a nutcracker to gently crack the husk and remove it. After husking, rinse the nuts thoroughly to remove any remaining husk debris.
Drying the Black Walnuts
After cleaning, the black walnuts need to be dried. Spread the nuts in a single layer on a screen or a tray in a well - ventilated area. Avoid direct sunlight, as it can cause the nuts to dry too quickly and develop a bitter taste. Stir the nuts every few days to ensure even drying. The drying process can take anywhere from two to four weeks, depending on the humidity and temperature.
Cracking the Tough Shells
Black walnut shells are extremely hard, but with the right techniques, you can crack them open to access the delicious nutmeat inside. One method is to use a vise. Place the walnut in the vise with the seam facing up and slowly tighten the vise until the shell cracks. Another option is to use a specialized nutcracker designed for black walnuts. These nutcrackers have a stronger grip and can handle the tough shells more effectively.
Once you've cracked the shell, use a nut pick or a small screwdriver to remove the nutmeat. Be careful not to break the nutmeat into small pieces, as larger pieces are more desirable for cooking and eating.
Storing Black Walnuts
After cracking and removing the nutmeat, store the black walnuts in an airtight container in the refrigerator or freezer. In the refrigerator, they can last for up to six months, while in the freezer, they can stay fresh for up to a year. Proper storage will help preserve the flavor and quality of the black walnuts.
In conclusion, harvesting and processing black walnuts can be a fun and rewarding activity. By following these guidelines on when and how to harvest, process, and crack the shells, you can enjoy the delicious taste of black walnuts in your favorite recipes. Whether you use them in baked goods, salads, or as a snack on their own, black walnuts are a versatile and nutritious addition to your diet.
