Ingredients:
1 pound chili peppers (stems removed) or other pepper
1 quart water
3 tablespoons salt
½-1 cup white wine vinegar
Instructions:
Roughly chop the peppers, then pack them into a ball jar, leaving at least 1 inch of head space. The peppers may rise a bit when fermenting. Mason jars are good to use as fermentation vessels as well.
Next, mix 1 quart unchlorinated water with 3 tablespoons sea salt. Pour just enough brine over the peppers to cover them, pressing them down a bit as you go. It is important to keep the peppers covered with the salt water brine to avoid spoilage. Check this daily.
( I use a crock that has a water seal for this stage).Screw on the lid and set the jar away from direct sunlight to ferment for at least 1 week. Ideal temperatures are between 55-75 degrees F. The most active fermentation period is between 1-2 weeks, so be sure to monitor it during this time. “Burp” the jars often by unscrewing the lid a bit to let out some of the accumulating gases. Or, use an airlock or membrane for easier fermenting.
After 1-2 weeks, the fermenting activity will diminish and the brine will turn cloudy and taste acidic, with a slightly sour flavour.
Drain the peppers, but reserve the brine.
Add the fermented peppers to a food processor or blender, along with 1/2 cup of the brine and 1/2 cup vinegar. You can add more or less of each as desired to your preference. More brine will have more salty flavor, more vinegar will be more acidic.
Blend until smooth.
Add the fermented hot sauce to a pot and bring to a quick boil. Reduce heat and simmer for 15 minutes. This will stop the fermentation process.
NOTE: You don’t have to cook the sauce if you don’t want to. It can be used as-is, though you will likely see some continued fermenting activity. If you decide to not cook it, store it in the refrigerator in sealed containers. You may need to burp them to release gas buildup every now and then, though refrigeration will slow the activity.
Strain the mixture to remove the solids if desired, or use as-is for a thicker hot sauce. Pour into hot sauce bottles and enjoy.
