To dry walnuts from a tree, spread them in a thin layer in a well-ventilated area, away from direct sunlight, for approximately two weeks until the shells are completely dried.
Here's a more detailed breakdown of how to properly dry walnuts harvested from a tree:
Steps for Drying Walnuts
-
Harvest Walnuts: Pick up walnuts that have fallen from the tree. Ideally, gather them daily to prevent mold and insect damage. Remove the outer green husk as soon as possible.
-
Clean the Walnuts: Wash the walnuts to remove any dirt, debris, or husk residue. This helps prevent mold growth during drying.
-
Curing/Drying Location: Choose a suitable drying location. Ideal spots include:
- Garage or Basement: These areas provide good air circulation and protection from direct sunlight.
- Outdoor Area (Weather Permitting): If there's no rain in the forecast, you can dry walnuts outdoors in a shaded area. Ensure protection from animals.
-
Drying Setup:
- Spread the cleaned walnuts in a single, thin layer. Use a tarp, wire mesh screen, clean plywood sheet, or another clean, dry surface. A wire mesh screen allows for better airflow.
- Avoid piling the walnuts on top of each other, as this can trap moisture and lead to mold.
-
Drying Time: Allow the walnuts to dry for approximately two weeks. The exact drying time depends on humidity and temperature.
-
Monitoring and Turning:
- Check the walnuts regularly (every few days) for any signs of mold or spoilage. Remove any affected nuts immediately.
- Turn the walnuts periodically to ensure even drying on all sides. This prevents moisture buildup and promotes faster drying.
-
Testing for Dryness:
- The walnuts are dry when the shell feels lightweight and brittle.
- You should hear the kernel rattle inside the shell when shaken.
- The kernel itself should snap cleanly when broken and not be rubbery.
-
Storage: Once completely dried, store the walnuts in a cool, dry, and well-ventilated location. Mesh bags, burlap sacks, or containers with good airflow are suitable for storage. Avoid storing them in airtight containers, which can trap moisture.
By following these steps, you can ensure that your walnuts are properly dried and stored, preserving their flavor and quality for consumption.
