Curing Fresh Olives at Home
Curing olives is a game of patience that strips the natural bitterness from the fruit using water, salt, or lye. For home use, the water-curing method is the most reliable, involving regular rinsing over several weeks until the bite fades, followed by a final soak in a seasoned brine.
Freshness determines your timeline
Raw olives are nearly inedible and require consistent maintenance. Ensure you have ample glass jars and enough space to store them while they soak.
- Large glass jars with sealable lids
- Sterilized knife or mallet
- Non-reactive storage containers
What goes in.
- 5 lbfresh, unblemished raw olives
- As neededfiltered water
- 1 cupcoarse sea salt (non-iodized)
- Optionalfresh bay leaves, lemon peels, or garlic cloves for final brine
Cracking vs. Slitting
Before curing, physically break the skin of each olive to allow water to penetrate the flesh. A quick crack with a mallet speeds the process significantly compared to simple slits.
The method.
Prepare the fruit
Wash the olives thoroughly. Use a mallet or the flat side of a knife to crack each olive once, being careful not to crush the pit.
Initiate the water bath
Place cracked olives in a jar and cover entirely with cold, filtered water. Use a weight to keep them submerged, as floating olives will oxidize and darken.
Daily refreshing
Drain and replace the water every day for the first two weeks. Taste one olive after 14 days; if it is still too bitter, continue the daily water change for another week.
Final brine
Once the bitterness is reduced to your preference, prepare a brine using 1 part salt to 10 parts water. Transfer olives to clean jars, add aromatics, and pour the brine over them.
When it doesn't go to plan.
Always use non-iodized salt, as iodine can discolor the fruit.
Keep jars in a cool, dark place during the curing process to prevent yeast buildup.
If you see a thin layer of white film on the surface during the final brining, skim it off; it is often just harmless kahm yeast.

How do I know if they are ready?
The flesh should lose its sharp, astringent quality and take on the characteristic texture of a jarred olive.
Can I use tap water?
Avoid heavily chlorinated water, as it can interfere with the curing process and impart an off-taste to the olives.
