Curing Raw Mediterranean Olives

Fresh olives off the branch are inedible due to their intense bitterness. This process removes that compound, leaving you with firm, salty fruit ready for the table.

Before you start

Patience is your primary ingredient.

The olives will be submerged for a long time; use glass containers to avoid metallic tastes and keep them in a cool, dark cupboard to prevent spoilage.

  • large glass jars with lids
  • cheesecloth
  • colander
The key technique

Slitting the Skin

You must cut the skin of each olive to allow the water to reach the flesh. A single shallow slit around the equator of the olive is sufficient.

Step by step

The method.

  1. Scarify the fruit

    Use a sharp paring knife to make one or two shallow slits into each olive. Do not cut to the pit.

  2. Begin the water soak

    Place olives in the jar and fill with cold, filtered water. Cover with cheesecloth and a lid. Change the water every single day for at least 14 days.

  3. Taste test

    After two weeks, bite into an olive. If it is still intensely bitter, keep changing the water for another week.

  4. Final brining

    Once the bitterness is mostly gone, move the olives to a brine of 1 part sea salt to 10 parts water. Add a splash of vinegar or lemon juice to stabilize.

Tips & troubleshooting

When it doesn't go to plan.

Tip

Always use non-iodized sea salt for the final brine to keep the liquid clear.

Tip

Ensure the olives stay fully submerged under the brine line; use a small weight if they float.

Tip

If you see a thin white film, it is usually harmless yeast, but rinse the olives thoroughly before serving.

Questions

The ones that keep coming up.

How do I know if the olives have spoiled?

If the olives become mushy or develop a strong, rancid, or 'off' odor that persists after rinsing, discard the entire batch.

Can I add herbs to the final brine?

Yes, once you move to the final salt brine, add lemon peel, rosemary sprigs, or bay leaves to the jar for extra character.
