How to Cure Walnuts

Curing walnuts helps remove the bitter tannins from the nuts and brings out their rich, flavorful taste. Here's a general method for curing walnuts:

1. Harvest at the Right Time: Walnuts are ready for harvesting when the outer green husk splits and the nuts fall out. Typically, this occurs in late summer to early fall.

2. Gather: Collect the fallen nuts, making sure to discard any that appear damaged or rotten. Remove any remaining husk material from the nuts.

3. Wash and Soak: Rinse the walnuts thoroughly under running water to remove dirt and debris. Soak the walnuts in a large container filled with cold water for 2-3 days, changing the water every day.

4. Rinse and Drain: After soaking, rinse the walnuts one more time and drain thoroughly. Discard any walnuts that float; these are likely to be bad.

5. Prepare the Brine: Make a brine solution by dissolving salt and sugar in boiling water. Use a ratio of about 1 tablespoon of salt and 1/4 cup of sugar per gallon of water. Allow the brine solution to cool completely.

6. Soak in Brine: Place the walnuts in a clean glass or ceramic container. Pour the cooled brine solution over the walnuts, making sure they are completely submerged. Weigh the walnuts down with a plate or something that fits snugly inside the container to keep them immersed in the brine.

7. Cure Time: Cover the container and store it in a cool, dark place, such as a pantry or cellar, for 4-6 weeks. During this time, the walnuts will absorb the brine and lose their bitterness.

8. Rinse and Dry: After the curing period is complete, remove the walnuts from the brine and rinse them well under running water. Spread them out on a clean towel or baking sheet and allow them to air dry completely.

9. Store: Once dry, store the cured walnuts in an airtight container in a cool, dry place. They will keep well for several months.

Note: Curing walnuts can also be done without the use of brine. In this case, you would simply spread the walnuts in a single layer on a baking sheet and bake them at 200°F (93°C) for 1-2 hours or until they are dry and crisp. This method is quicker but may not remove as much of the bitterness as the brine method.
