What You Need to Know
The movement of capsaicin‑rich chilies, lactic‑fermenting grains, acidic condiments, and koji‑based soy sauces illustrates how chemical stability, fermentation parameters, and failure modes (e.g., mold, aflatoxin) are governed by temperature, pH, and humidity in new cultural contexts.
