Homemade Fermented Hot Sauce (Print Version)

Tangy lacto-fermented hot sauce with complex heat and bright acidity—ready after a week of fermentation.

# Components:

→ Peppers

01 - 10 oz (by weight) fresh red chili peppers (Fresno, jalapeño, serrano or a mix), stems removed
02 - 1 small red bell pepper, stem and seeds removed

→ Vegetables & Aromatics

03 - 4 garlic cloves, peeled
04 - 1 small shallot or 1/2 small onion, peeled
05 - 1 medium carrot, peeled and sliced (optional)

→ Brine

06 - 2 cups filtered water
07 - 1 tbsp non-iodized salt (sea salt or kosher salt)

→ Finishing

08 - 2 tbsp apple cider vinegar or distilled white vinegar

# Directions:

01 - Dissolve 1 tablespoon non-iodized salt in 2 cups filtered water, stirring until fully dissolved; set the brine aside to cool if warm.
02 - Coarsely chop the red chilies and red bell pepper; halve or slice the carrot; crush the garlic cloves and quarter the shallot or onion to help release flavor.
03 - Place all chopped vegetables and aromatics into a clean 1-quart glass jar, packing gently to eliminate large air pockets.
04 - Pour the prepared brine over the contents until everything is fully submerged; weigh the solids down with a fermentation weight or a small zip-top bag filled with brine to keep them beneath the liquid.
05 - Cover the jar loosely with the lid or fit a fermentation airlock so gases can escape while preventing contaminants from entering.
06 - Place the jar in a cool, dark location at roughly 65–72°F and ferment for 7 days; check once daily to ensure vegetables remain submerged and skim any surface scum or mold.
07 - After 7 days, transfer the fermented vegetables and brine to a blender; add 2 tablespoons vinegar and blend to a smooth consistency, adding additional brine or vinegar to thin if desired.
08 - If a smooth sauce is preferred, pass the blended mixture through a fine-mesh sieve, pressing to extract as much liquid as possible; for a rustic texture, leave unstrained.
09 - Pour the finished sauce into a sterilized bottle or jar, seal, and refrigerate; the sauce keeps for up to 3 months and will continue to develop flavor over time.

# Expert Advice:

  • There’s a quiet pride in pouring a sauce you coaxed to life onto your meal—the kind you want to tell your spice-loving friends about.
02 -
  • If you don’t keep the veggies fully submerged, strange things can grow—learned that after attempting to fish out a rogue chili midweek.
