Before you start

Patience is your primary ingredient

Different varieties require different methods, but the water-cure is the most forgiving for beginners. Expect the olives to remain bitter for several weeks before the transformation sets in.

  • Non-reactive weights or small plates

The key technique

Leaching the Bitterness

The secret to a successful cure is consistent water changes to draw out the oleuropein; if you miss a day, the bitterness will stall in the fruit.

Step by step

The method.

  1. Prepare the fruit

    Sort through your harvest and discard any bruised or damaged fruit. Use a clean needle to prick each olive twice to allow the water to penetrate the skin.

  2. The first soak

    Place olives in a large glass jar and cover completely with cold water. Place a small plate on top to keep them submerged. Change the water every single day for two weeks.

  3. Taste test

    After two weeks, bite into one. If the bitterness is still sharp, continue the daily water changes for another week. The fruit should feel softened.

  4. Prepare the brine

    Create a brine using a 1:10 ratio of sea salt to water. Boil the water to dissolve the salt, then let it cool completely before pouring over the drained olives.

  5. Final cure

    Seal the jars and store them in a cool, dark place. Wait at least one month before serving. The olive flesh should be firm but no longer acrid.

Tips & troubleshooting

When it doesn't go to plan.

Tip

Always ensure the olives stay submerged beneath the surface of the brine to prevent mold.

Tip

Add strips of lemon peel or sprigs of dried rosemary to the jar during the final brine stage for added character.

Tip

If you see a thin white film on the surface, skim it off, but if the brine becomes cloudy and smells sour, discard the batch.

Questions

The ones that keep coming up.

Can I use iodized table salt?

Avoid it. The additives in table salt can cloud your brine and may darken the color of the olives.

Why did my olives turn soft?

Softness usually indicates the water was too warm during the initial soaking phase or the fruit was over-ripe at harvest.
