What You Need to Know
During fermentation, lactic acid bacteria metabolize sugars to produce lactic acid, lowering the pH to 4.5–5.0 and inhibiting spoilage microbes. The porous clay allows heat to rise to 60–70 °C, promoting collagen and starch gelatinization while retaining moisture. The sealed environment limits oxygen, further reducing oxidation and preserving the stew’s texture and flavor.
