What You Need to Know
The initial sear at ~140 °C initiates Maillard browning, forming melanoidins and aromatic heterocycles. A subsequent 80–90 °C simmer for 2–3 hours hydrolyzes collagen into gelatin, denatures proteins, and leaches minerals such as iron and zinc into the broth, yielding a tender, nutrient‑dense dish.
