Which Salt to Use
Pickling Salt
Dissolves clearly, no cloudiness
Fine Sea Salt
Good choice, may cloud brine slightly
Kosher Salt
Works well, adjust for larger crystals
Table Salt
Anti-caking agents cloud brine
Adjusting Salt for Your Conditions
Half-sour picklesUse 2.5-3% brine, ferment 3-5 days
Full-sour picklesUse 3.5-5% brine, ferment 1-3 weeks
Hot weatherUse higher salt (4-5%) to slow fermentation
Extra crunchy picklesAdd grape or oak leaves, use calcium chloride
Common Salt Mistakes to Avoid
- Using too little salt (soft, slimy pickles)
- Not keeping pickles fully submerged
- Using tap water with chlorine
- Fermenting in direct sunlight
Pro Tips
- Use filtered or spring water - chlorine kills fermentation
- Add tannin-containing leaves (grape, oak, horseradish) for crunch
- Use fresh, firm cucumbers - not waxy supermarket ones
- Pickle within 24 hours of harvest for best results
Frequently Asked Questions
What is the difference between half-sour and full-sour pickles?
Half-sour pickles are fermented briefly (3-5 days) and are still somewhat cucumber-like. Full-sour pickles ferment longer (1-3 weeks) and are fully tangy throughout.
Why are my pickles soft instead of crunchy?
Soft pickles usually result from too little salt, too warm temperatures, or using old cucumbers. Adding tannin-rich leaves helps maintain crunch.
Do I weigh the salt or the water?
The percentage is based on water weight. For 1 liter (1000g) of water at 3.5%, use 35g of salt.
