What You Need to Know
The process hydrolyzes collagen into gelatin at 85–90 °C for 2–3 h, then concentrates flavor by reducing the broth at 95–100 °C for 30–45 min. Adding vegetables after 90 min preserves their enzymes and limits starch gelatinization, yielding a clear, viscous soup characteristic of royal Babylonian cuisine.
The Science
Primary Reaction
thermal hydrolysis of collagen to gelatin and Maillard‑type flavor development during reduction
