Fermented Hot Sauce — Louisiana Style

Lacto-fermentation transforms fresh chillies into something with depth, complexity, and a gentle tang. This is the base technique behind most of the world's great hot sauces.

Ingredients

• 500g fresh red chillies (cayenne, bird's eye, or tabasco work well)
• 3 cloves garlic
• 1 tbsp non-iodised salt (about 2% of total weight)
• Water (filtered or bottled — chlorine kills fermentation)

Method

Blend chillies, garlic, and salt into a rough mash. Transfer to a clean glass jar. Push the mash below the surface with a weight.

Ferment at room temperature (18–24°C) for 7–14 days. Burp the jar daily. You'll see bubbles within 24–48 hours — that's lacto-bacteria at work.

After fermentation, blend the mash with white vinegar (start with 100ml and adjust). Strain for a smoother sauce, or leave textured.

What to expect

The sauce will be tangier, deeper, and more complex than a cooked sauce. The fermentation develops lactic acid, which adds subtle sourness and preserves the sauce naturally.

Storage

Refrigerate. Properly fermented sauce keeps for 6–12 months.
