Olive Pickling

Ingredients

Directions

Prepare

  1. Pick the olives, grouping by color: all green, all red, or black.

  2. Dissolve the lye in a small amount of boiling water.

Soak and rinse

  1. Submerge the olives in the lye solution for 3 days, stirring several times daily.

  2. Soak the olives in fresh water for 4 days, changing the water at least twice daily.

Brine

  1. When the bitterness is gone, cover the olives with brine made from 1 pint of salt to 1 gallon of water, ensuring all olives are submerged.

What each ingredient does

Olives
The fruit being treated; its bitterness is removed so it can be eaten.
Concentrated lye
Breaks down the bitter compounds in the raw olive flesh during the soak.
Salt
Forms the brine that preserves the olives after the bitterness is removed.

The step that matters

Rinsing out the lye. Lye keeps working on the olives until it is washed out. Changing the fresh water often removes leftover lye and dissolved bitter compounds, so the olives do not taste harsh or caustic when the bitterness is gone.
