Kosher Salt
Good choice, adjust for flake size
Pickling Salt

Anti-caking agents affect flavor
Adjusting Salt for Your Conditions
Mash method (no brine)Use 2-2.5% salt by weight of peppers
Brine methodUse 3% brine to cover peppers
Including fruitsMay need slightly more salt due to sugars
Longer fermentation (2+ weeks)Use 3% for stability
Common Salt Mistakes to Avoid
- Using too little salt (risk of off-flavors or mold)
- Not keeping peppers submerged under brine
- Using metal containers that react with acid
- Sealing too tightly without burping (pressure buildup)
Pro Tips
- Weigh total ingredients (peppers, garlic, onions) and calculate 2.5% salt
- Wear gloves when handling hot peppers
- Blend peppers coarsely before fermenting for more surface area
- Add vinegar after fermentation for extra tang and shelf stability
Frequently Asked Questions
Should I use a mash or brine method?
Mash method (salted ground peppers) is traditional for hot sauce. Brine method (whole peppers in saltwater) works too. Mash ferments faster and is easier to blend.
Can I add other ingredients during fermentation?
Yes! Garlic, onions, carrots, and fruit all ferment well with peppers. Add them at the start and include their weight in your salt calculation.
How do I know when hot sauce fermentation is done?
Minimum 5-7 days, but 2-4 weeks develops more complex flavor. Taste regularly. When bubbling slows and flavor is where you want it, blend and bottle.
