What You Need to Know
Braising at sub‑boiling temperatures (88–93 °C) hydrolyzes the triple‑helix collagen into gelatin, a process accelerated by the acidic tomato sauce (pH≈4.5) and heat. The resulting gelatin network locks moisture, while Maillard‑derived flavor compounds from spices and surface browning add depth. Precise temperature, time, and resting are essential to achieve a sliceable yet tender texture.
