Sort and clean: Discard overripe or damaged olives. Rinse thoroughly under cold water, using a colander if convenient.
Crack or slice: Slightly crack each olive with a knife or make a gentle slice for better flavor absorption and even brine penetration.
Soak in water: Place olives in a bowl of cool water. Change the water daily for 10 to 14 days, depending on the olive variety, to remove bitterness.
Brine solution: Dissolve 1/2 cup of salt in a gallon of water to create a concentrated salt solution.
Brine bath: Submerge prepared olives in the brine solution, ensuring they are completely covered. Leave them in brine for an additional 10 to 14 days for flavor and preservation.
Freezing olives:
Drain and dry: Remove olives from the brine solution and drain thoroughly. Pat them dry with a clean kitchen towel.
Portion: Divide dry olives into portion sizes suitable for your needs to make defrosting easier.
Packaging: Place olives in airtight freezer bags or containers. Remove excess air to prevent freezer burn.
Label and date: Clearly label bags or containers with the olive type and freezing date to track storage time.
Freeze: Put olives in the freezer. They can be stored for up to six months, with optimal flavor and texture within the first three months.
