Walnuts can also be cracked and eaten. Their hulls and husks are very tough, so a hammer and chisel or vise grip is needed to break them and remove the nutmeat.

  1. Hull the nuts
  2. The first step is to hull the walnuts slated for drying. Hulls are dense and thick, so letting them soften for a day or so ahead of time is advisable. Nuts can then be hulled with a hammer or with a press or vise grip.

  3. Wash the hulled nuts
  4. Once the requisite number of nuts has been hulled, they must be washed. This can be done with a high-powered hose or a power washer. Either works to blast away detritus and get the nuts ready for drying.

  5. Dry the nuts
  6. The final step is to lay the nuts, evenly spaced, on wire racks in a location with an ambient temperature of 95 to 100 degrees Fahrenheit. The nuts will dry in 3 to 4 days and will then be ready to store.
