A tangy, flavorful fermented hot sauce made with fresh peppers, garlic, and sea salt that adds a probiotic punch and vibrant zest to any meal. This easy step-by-step guide helps you create a balanced, spicy, and slightly sweet sauce with simple ingredients and minimal hands-on time.

Ingredients

Scale
  • 1 lb fresh hot peppers (jalapeños and fresnos recommended)
  • 45 medium garlic cloves, peeled
  • 2 tablespoons sea salt (non-iodized, e.g., Celtic sea salt)
  • 2 cups filtered water (chlorine-free)
  • Optional: 1 small carrot, peeled and chopped
  • Optional: 1 small onion, roughly chopped
  • Optional: 1 tablespoon apple cider vinegar
  • Optional: 1 teaspoon fresh or dried oregano or thyme

Instructions

  1. Dissolve 2 tablespoons of sea salt in 2 cups (480 ml) of filtered water. Stir until fully dissolved and set aside.
  2. Rinse peppers thoroughly, remove stems, and roughly chop. Keep seeds for more heat or remove for milder sauce.
  3. Peel and chop garlic, carrot, and onion if using.
  4. Add chopped peppers, garlic, carrot, and onion to a blender. Pour in half of the brine (about 1 cup / 240 ml). Blend until smooth and thick. Add remaining brine as needed to blend.
  5. Pour the pepper puree into a 1-quart glass fermentation jar, leaving about 1 inch of headspace.
  6. Use a fermentation weight or smaller jar to press the mixture below the brine line. Add more brine if needed to keep submerged.
  7. Cover the jar with an airlock lid or a cloth secured with a rubber band to allow gases to escape.
  8. Ferment at room temperature (65°F to 75°F) in a cool, dark place for 7 to 14 days. Check daily for bubbling and skim off any white film (kahm yeast).
  9. After 7 days, taste the sauce. If tangy and fizzy enough, proceed; otherwise, ferment longer.
  10. Optional: Blend again and strain through a fine mesh for a smoother sauce. Add 1 tablespoon apple cider vinegar for extra tang if desired.
  11. Transfer to a clean jar, seal tightly, and refrigerate. Sauce keeps for up to 6 months and develops more flavor over time.

Notes

[‘Use non-iodized sea salt for best fermentation results.’, ‘Keep peppers submerged under brine to prevent mold.’, ‘Ferment at room temperature between 65°F and 75°F.’, ‘Skim off harmless kahm yeast if it forms on the surface.’, ‘Discard batch if colored mold (pink, black, fuzzy) appears.’, ‘Stir gently every few days to redistribute flavors and gases.’, ‘Adjust heat by using different peppers or removing seeds.’, ‘For a quicker ferment, reduce fermentation time to 3-5 days and refrigerate.’, ‘Add herbs or spices to customize flavor.’, ‘Avoid boiling sauce after fermentation to preserve probiotics.’]
