Curing Fresh Olives at Home
Curing olives is a game of patience that strips the intense bitterness from raw fruit using water or brine. You crack or slit the fresh olives to allow the process to penetrate the flesh, then soak them in repeated changes of water until the bitterness dissipates, followed by a final, lasting brine in a glass jar.
Freshness determines the timeline
Raw olives straight from the tree are inedible. Choose firm, unblemished fruit and commit to the daily water changes to ensure you don't grow mold during the process.
- heavy rolling pin or meat mallet
- glass jars with tight lids
- non-reactive bowls
What goes in.
- 5 lbfresh, raw green olives
- As neededcold filtered water
- 1 cupcoarse sea salt
- 1/2 cupwhite wine vinegar
Breaking the Skin
Use a heavy object to gently crack the olive flesh without shattering the pit. This creates a direct channel for the water to leach out the oleuropein, which is the compound responsible for the raw, sharp bitterness.
The method.
Preparation
Wash the olives thoroughly under cold water. Discard any fruit that has soft spots or insect holes.
Cracking
Place an olive on a clean towel and tap it firmly with a mallet until the skin splits. Immediately drop the cracked olive into a large bowl of cold water.
The Soak
Keep the olives completely submerged in the water using a small plate to weight them down. Change the water completely every 24 hours for 10 to 14 days.
Taste Test
At the two-week mark, bite into one. If the bitterness is gone to your liking, move to the brine. If not, continue the daily soak.
Final Brine
Mix a ratio of 10 parts water to 1 part sea salt. Pack the olives into clean jars, add the vinegar, and fill with the brine until the olives are fully covered. Seal tightly.
When it doesn't go to plan.
Always use non-reactive containers like glass or food-grade plastic; metal will react with the brine and ruin the flavor.
If you see a thin white film on the surface during the soaking phase, discard that water and rinse the olives well before adding fresh water.
The olives are ready to eat after sitting in the final brine for at least one week, but they continue to improve in texture for another month.
The ones that keep coming up.
How do I know if they are spoiled?
If the olives become mushy or develop a sharp, unpleasant odor like rotting vegetation, discard the entire batch.
Can I add herbs to the final brine?
Yes, once you reach the final brining stage, feel free to add lemon slices, garlic cloves, or fresh fennel seeds to the jar.
