What You Need to Know
Roasting dried red chilies at 120–140 °C caramelizes sugars and partially degrades capsaicin, reducing pungency while preserving heat. Sautéing onions and garlic at 60–70 °C initiates Maillard reactions, producing sweet‑smoky flavor compounds. Acidification with lime juice (citric acid) and salting lowers pH to ~3.5, inhibiting pathogens, and subsequent lactic‑acid fermentation further reduces pH to 3.2–3.4, adding mild sourness.
