Psilolia Olives Choose small firm green olives, wash well, and place in 10% -14% brine to remove bitterness. They can be kept in this until ready for eating. A little oil can be added, if desired.
Neratzolies Lightly score olives in 2-3 places, wash and soak them in water for one month (without changing it), to remove bitterness.

These olives can also be preserved in equal parts 10% brine and bitter orange or lemon juice.
