Lacto-Fermented Hot Sauce: dry salt or brine, 7.0 days at 2.50% salt

Any combination of hot peppers + complementary aromatics (garlic, onion, salt) fermented to tang, then blended smooth with vinegar to adjust final pH. Tabasco, Crystal, and many craft hot sauces use this base method. Final pH <3.5 + bottling = shelf-stable 6-12 months refrigerated.

Technique

Remove stems from peppers (keep seeds for heat, remove for milder). Weigh. Add 2.5% salt by vegetable weight. Puree or chop coarse. Pack in jar with optional garlic + onion + carrot (sweetens). Cover with minimal brine if not self-brining (some peppers release plenty, some don't). Airlock lid. Ferment 7-14 days at 70°F. Blend smooth. Add white vinegar to taste (usually 10-20% of final weight) to drop pH to 3.0-3.5. Strain if desired. Bottle. Refrigerate.
