Homemade Fermented Hot Sauce (Printable)

Fiery, tangy lacto-fermented hot sauce with garlic and carrot for depth; yields ~2 cups and stays fresh in the fridge.

# What You'll Need:

→ Peppers

01 - 10 oz fresh red chili peppers, stems removed (Fresno, jalapeño, serrano, or a mix)
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 tablespoon non-iodized salt (sea salt or kosher salt)

→ Finishing

08 - 2 tablespoons apple cider vinegar or distilled white vinegar

# How to Make It:

01 - Dissolve 1 tablespoon non-iodized salt into 2 cups filtered water, stirring until fully dissolved. Set the brine aside at room temperature.
02 - Coarsely chop the chili peppers, red bell pepper, carrot, garlic and shallot (or onion) so they will fit comfortably into the jar and blend easily later.
03 - Place the chopped vegetables and aromatics into a clean 1-quart glass jar, pressing them down to remove air pockets; leave about 1 inch of headspace at the top.
04 - Pour the prepared brine over the packed vegetables until fully submerged. Use a fermentation weight or a small zip-top bag filled with brine to keep the solids below the liquid surface.
05 - Loosely fit the lid or install an airlock to allow gases to escape. Store the jar in a cool, dark place at about 65–72°F and ferment for 7 days, checking daily to ensure the solids remain submerged and skimming any surface scum if needed.
06 - After 7 days, transfer the fermented vegetables and their brine to a blender. Add 2 tablespoons vinegar and blend until smooth, adding additional brine or vinegar to reach your desired consistency.
07 - For a silky finish, pass the blended mixture through a fine-mesh sieve, pressing to extract as much liquid as possible. If you prefer a rustic texture, skip this step.
08 - Pour the finished sauce into a sterilized bottle or jar, seal, and refrigerate. The flavor will continue to develop; keep refrigerated and use within 3 months.

# Expert Suggestions:

01 -
  • This hot sauce develops a unique, complex flavor that store-bought bottles just can't match.
  • It's thrilling to watch your kitchen transform peppers into something unexpected (and spicy) with just time and patience.
02 -
  • Once I used tap water and had to toss a batch—chlorine can sabotage your ferment before it starts.
  • Adding even a pinch too little salt makes it risky; stick to the recipe and the good bacteria will reward you.
03 -
  • Using gloves while prepping peppers saves you from spicy surprises hours later.
  • Start checking for flavor at day five, especially if your kitchen is warm—the sauce can ferment faster than you expect.
